This patch extends the SVE UNSPEC_SEL patterns so that they can use:
(1) MOV /M of a duplicated integer constant
(2) MOV /M of a duplicated floating-point constant bitcast to an integer,
accepting the same constants as (1)
(3) FMOV /M of a duplicated floating-point constant
(4) MOV /Z of a duplicated integer constant
(5) MOV /Z of a duplicated floating-point constant bitcast to an integer,
accepting the same constants as (4)
(6) MOVPRFXed FMOV /M of a duplicated floating-point constant
We already handled (4) with a special pattern; the rest are new.

This patch handles more predicate constants by using TRN1, TRN2
and EOR. For now, only one operation is allowed before we fall
back to loading from memory or doing an integer move and a compare.
The EOR support includes the important special case of an inverted
predicate.
The real motivating case for this is the ACLE svdupq function,
which allows a repeating 16-bit predicate to be built from
individual scalar booleans. It's not easy to test properly
before that support is merged.

The remaining uses of UNSPEC_MERGE_PTRUE were in integer comparison
patterns. These aren't actually merging operations but zeroing ones,
although there's no practical difference when the predicate is a PTRUE.
All comparisons produced by expand are predicated on a PTRUE,
although we try to pattern-match a compare-and-AND as a predicated
comparison during combine.
Like previous patches, this one rearranges things in a way that works
better with the ACLE, where the initial predicate might or might not
be a PTRUE. The new patterns use UNSPEC_PRED_Z to represent zeroing
predication, with a aarch64_sve_ptrue_flag to record whether the
predicate is all-true (as for UNSPEC_PTEST).
See the block comment in the patch for more details.

The SVE patterns used an UNSPEC_MERGE_PTRUE unspec to attach a predicate
to an otherwise unpredicated integer arithmetic operation. As its name
suggests, this was designed to be a wrapper used for merging instructions
in which the predicate is known to be a PTRUE.
This unspec dates from the very early days of the port and nothing has
ever taken advantage of the PTRUE guarantee for arithmetic (as opposed
to comparisons). This patch replaces it with the less stringent
guarantee that:
(a) the values of inactive lanes don't matter and
(b) it is valid to make extra lanes active if there's a specific benefit
Doing this makes the patterns suitable for the ACLE _x functions, which
have the above semantics.
See the block comment in the patch for more details.

The SVE int<->float conversion patterns need to handle various
combinations of modes, making sure that the predicate mode is based
on the widest element size. We did this using separate patterns for
conversions involving:
- HF (converting to/from [HSD]I, predicated based on the int operand)
- SF (converting to/from [SD]I, predicated based on the int operand)
- DF (converting to/from [SD]I, predicated based on the float operand)
This worked, and meant that there were no redundant patterns. However,
the ACLE needs various new predicated patterns too, and having three
versions of each one seemed excessive.
This patch instead splits the patterns into two groups rather than three.
For conversions to integers:
- truncating (predicated based on the source type, DF->SI only)
- non-truncating (predicated based on the destination type)
For conversions from integers:
- extending (predicated based on the destination type, SI->DF only)
- non-extending (predicated based on the source type)
This means that we still don't create pattern names for the invalid
combinations DF<->HI and SF<->HI. The downside is that we need to
use C conditions to exclude the SI<->DF case from the non-truncating/
non-extending patterns. We therefore have two pattern names for SI<->DF,
but genconditions ensures that the invalid one always has the value
CODE_FOR_nothing.

predicate has to be taken literally, or whether it is valid to
make extra lanes active (up to and including using a PTRUE).
This again is laying the groundwork for the ACLE patterns,
in which the value can depend on the FP command-line flags.
At the moment it's only needed for addition, subtraction and
multiplication, which have unpredicated forms that can only
be used when operating on all lanes is safe. But in future
it might be useful for optimising predicate usage.
The strict mode requires extra alternatives for addition,
subtraction and multiplication, but I've left those for the
main ACLE patch.

This patch generalises the SVE BIC pattern so that it doesn't
rely on REG_EQUAL notes. The danger with relying on the notes
is that an optimisation could for example replace the original
(not ...) note with an (unspec ... UNSPEC_MERGE_PTRUE) in which
the predicate is a constant. That's a legitimate change and
could even be useful in some situations.
The patch also makes the operand order match the SVE operand order in
both the vector and predicate BIC patterns, which makes things easier
for the ACLE.

This patch makes sure that we build all SVE predicate constants as
VNx16BI before RA, to encourage similar constants to be reused
between modes. This is also useful for the ACLE, where the single
predicate type svbool_t is always a VNx16BI.
Also, and again to encourage reuse, the patch makes us use a .B PTRUE
for all ptrue-predicated operations, rather than (for example) using
a .S PTRUE for 32-bit operations and a .D PTRUE for 64-bit operations.
The only current case in which a .H, .S or .D operation needs to be
predicated by a "strict" .H/.S/.D PTRUE is the PTEST in a conditional
branch, which an earlier patch fixed to use an appropriate VNx16BI
constant.

This patch reworks the rtl representation of the SVE PTEST operation
so that:
- the governing predicate is always VNx16BI (and so all bits are defined)
- it is still possible to pattern-match the governing predicate in the
mode that it had previously
- a new hint operand says whether the governing predicate is known to be
all true for the element size of interest, rather than this being part
of the unspec name.
These changes make it easier to handle more flag-setting instructions
as part of the ACLE work.

We were shoe-horning all built-in enumerations (including frontend
and target-specific ones) into a field of type built_in_function. This
was accessed as either an lvalue or an rvalue using DECL_FUNCTION_CODE.
The obvious danger with this (as was noted by several ??? comments)
is that the ranges have nothing to do with each other, and targets can
easily have more built-in functions than generic code. But my patch to
make the field bigger was the straw that finally made the problem visible.
This patch therefore:
- replaces the field with a plain unsigned int
- turns DECL_FUNCTION_CODE into an rvalue-only accessor that checks
that the function really is BUILT_IN_NORMAL
- adds corresponding DECL_MD_FUNCTION_CODE and DECL_FE_FUNCTION_CODE
accessors for BUILT_IN_MD and BUILT_IN_FRONTEND respectively
- adds DECL_UNCHECKED_FUNCTION_CODE for places that need to access the
underlying field (should be low-level code only)
- adds new helpers for setting the built-in class and function code
- makes DECL_BUILT_IN_CLASS an rvalue-only accessor too, since all
assignments should go through the new helpers

This patch protects various uses of DECL_FUNCTION_CODE that didn't
obviously check for BUILT_IN_NORMAL first (either directly or in callers).
They could therefore trigger for functions that either aren't built-ins

Also, the patch removes a redundant GIMPLE_CALL check from
optimize_stdarg_builtin, since it gave the impression that the stmt
was less well checked than it actually is.

This patch is a combination of two changes that have to be
committed as a single unit:
(1) Try to fold IFN_WHILE_ULTs with constant arguments to a VECTOR_CST
(which is always possible for fixed-length vectors but is not
necessarily so for variable-length vectors)
(2) Make the SVE port recognise constants that map to PTRUE VLn,
which includes those generated by the new fold.
(2) can't be tested without (1) and (1) would be a significant
pessimisation without (2).
The target-specific parts also start moving towards doing predicate
manipulation in a canonical VNx16BImode form, using rtx_vector_builders.
