For partial SVE vectors of element X, we want to treat duplicates
of single X elements in the same way as for full vectors of X.
But if a constant instead contains a repeating pattern of X elements,
the transition from one value to the next must happen at container
boundaries rather than element boundaries. E.g. a VNx4HI should
in that case contain the same number of constants as a VNx4SI.
Fixing this means that we need a reinterpret from the container-based
mode to the partial mode; e.g. in the above example we need a
reinterpret from VNx4SI to VNx4HI. We can't use subregs for that
because they're forbidden by aarch64_can_change_class_mode; we should
handle them in the same way as for big-endian instead.

Partial SVE modes can be picked up and used by the vector_size(N)
attribute.[*] This means that we need to cope with arguments and return
values with partial SVE modes, which previously triggered asserts like:
/* Generic vectors that map to SVE modes with -msve-vector-bits=N are
passed by reference, not by value. */
gcc_assert (!aarch64_sve_mode_p (mode));
The ABI for these types is fixed from pre-SVE days, and must in any case
be the same for all -msve-vector-bits=N values. All we need to do is
ensure that the vectors are passed and returned in the traditional way.
[*] Advanced SIMD always wins for 64-bit and 128-bit vectors though.

The SVE port needs to maintain a different type identity for
GNU vectors and "SVE vectors" even during LTO, since the types
use different ABIs. The easiest way of doing that seemed to be
to use type attributes. However, these type attributes shouldn't
be user-facing; they're just a convenient way of representing the
types internally in GCC.
There are already several internal-only attributes, such as "fn spec"
and "omp declare simd". They're distinguished from normal user-facing
attributes by having a space in their name, which means that it isn't
possible to write them directly in C or C++.
Taking the same approach mostly works well for SVE. The only snag
I've hit so far is that the new attribute needs to (and only exists to)
affect type identity. This means that it would normally get included
in mangled names, to distinguish it from types without the attribute.
However, the SVE ABI specifies a separate mangling for SVE vector types,
rather than using an attribute mangling + a normal vector mangling.
So we need some way of suppressing the attribute mangling for this case.
There are currently no other target-independent or target-specific
internal-only attributes that affect type identity, so this patch goes
for the simplest fix of skipping mangling for attributes whose names
contain a space. Other options I thought about were:
(1) Also make sure that targetm.mangled_type returns nonnull.
(2) Check directly for the target-specific name.
(3) Add a new target hook.
(4) Add new information to attribute_spec. This would be very invasive
at this stage, but maybe we should consider replacing all the boolean
fields with flags? That should make the tables slightly easier to
read and would make adding new flags much simpler in future.

This patch adds support for associating a diagnostic message with an
optional diagnostic_metadata object, so that plugins can add extra data
to their diagnostics (e.g. mapping a diagnostic to a taxonomy or coding
standard such as from CERT or MISRA).
Currently this only supports associating a CWE identifier with a
diagnostic (which is what I'm using for the warnings in the analyzer
patch kit), but adding a diagnostic_metadata class allows for future
growth in this area without an explosion of further "warning_at"
overloads for all of the different kinds of custom data that a plugin
might want to add.
This version of the patch renames the overly-general
-fdiagnostics-show-metadata to -fdiagnostics-show-cwe and adds test
coverage for it via a plugin.
It also adds a note to the documentation that no GCC diagnostics
currently use this; it's a feature for plugins (and, at some point,
I hope, the analyzer).
