Both driver-i386.c and libgcc use CPUID to detect the processor name
as well as available ISAs. To detect the same processor or ISAs, the
same detection logic is duplicated in 2 places. Sometimes only one place
was up to date or got it right. Sometimes both places got it wrong.
1. Add common/config/i386/i386-isas.h to define _isa_names_table.
2. Use isa_names_table to auto-generate ISA command-line options.
3. Use isa_names_table to auto-generate __builtin_cpu_supports tests.
4. Use common/config/i386/cpuinfo.h to check available ISAs and detect
newer Intel processors in driver-i386.c and builtin_target.c.
5. Detection of AMD processors and older processors in driver-i386.c is
unchanged.

In i386-builtins.c, arch_names_table is used to to map architecture name
string to internal model. A switch statement is used to map internal
processor name to architecture name string and internal priority.
model and priority are added to processor_alias_table so that a single
entry contains architecture name string, internal processor name,
internal model and internal priority. 6 entries are appended for
i386-builtins.c, which have special architecture name strings: amd,
amdfam10h, amdfam15h, amdfam17h, shanghai and istanbul, and pta_size is
adjusted to exclude them. Entries which are not used by i386-builtins.c
have internal model 0. P_PROC_DYNAMIC is added to internal priority to

This makes sure to emit SLP vectorized loads where the first scalar
load is. This makes SLP dependence checking more powerful because
hoisting loads can use TBAA and it increases the freedom for
vector placement when there are constraints from live lanes.
Vectorized shifts block inserting vectorized stmts always after
vectorized defs because it ends up using the original scalar
operand even when the SLP graph indicates the shift operand
is vectorized (and we actually emit and cost those stmts).
vect_slp_analyze_and_verify_node_alignment shows we need alignment
for too many places, this is a temporary solution and my plan
is to have a single meta-info for a dataref group instead
(also getting rid of DR_GROUP_FIRST/NEXT_ELEMENT).

As reported in bugzilla when the -mcmse option is used while compiling for size
(-Os) with a thumb-1 target the generated code will clear the registers r7-r10.
These however are callee saved and should be preserved accross ABI boundaries.
The reason this happens is because these registers are made "fixed" when
optimising for size with Thumb-1 in a way to make sure they are not used, as
pushing and popping hi-registers requires extra moves to and from LO_REGS.
To fix this, this patch uses 'callee_saved_reg_p', which accounts for this
optimisation, instead of 'call_used_or_fixed_reg_p'. Be aware of
'callee_saved_reg_p''s definition, as it does still take call used registers
into account, which aren't callee_saved in my opinion, so it is a rather
misnoemer, works in our advantage here though as it does exactly what we need.
Regression tested on arm-none-eabi.
Is this OK for trunk? (Will eventually backport to previous versions if stable.)

This renames the command line options, the internal names, and mentions
in the comments, from "future" to "power10". Also, the file "future.md"
is renamed.
The predefined user macro _ARCH_PWR_FUTURE is renamed to _ARCH_PWR10.
"Future architecture" is renamed to "ISA 3.1".

Using parameter packs with function typedefs tripped a Clang bug
in which the packs were not being expanded correctly:
https://bugs.llvm.org/show_bug.cgi?id=46377
Work around that by going back to the decltype approach, but adding
a cast to void to suppress a warning about unused values.

* coretypes.h (first_type): Delete.
* recog.h (insn_gen_fn::operator()): Go back to using a decltype.
In GCC testsuite the MVE scalar shift execution tests (mve_scalar_shifts[1-4].c) are failings
because of executing them on target hardware which doesn't support MVE instructions. This patch
restricts those tests to execute only on target hardware that support MVE instructions.
