This patch allows the use of __vector_quad and __vector_pair, PPC MMA builtin
types, on all PowerPC 64-bit compilation units. When these types are
made available the builtins that use them automatically become available
so semantic checking for mma and pair vector memop __builtins is also
expanded to ensure these builtin function call are only allowed on
Power10 and new architectures. All related test cases are updated to
ensure test coverage.

The builtins: `__compare_and_swaplp`, `__fetch_and_addlp`,

The __darn family of builtins are only available on Pwr9,

This patch adds range checking for some Power10 altivec builtins and
changes the signature of a builtin to match documentation. For `vec_cntm`,
range checking is done via SemaChecking. For `vec_splati_ins`, the second
argument is masked to extract the 0th bit so that we always receive either a `0`
or a `1`.

When building in C mode, the VC runtime assumes that it can use pointer
aliasing through `char *` for the parameter to `__va_start`. Relax the
checks further. In theory we could keep the tests strict for non-system
header code, but this takes the less strict approach as the additional
check doesn't particularly end up being too much more helpful for
correctness. The C++ type system is a bit stricter and requires the
explicit cast which we continue to verify.
Add builtin and intrinsic for `__addex`.
This patch is part of a series of patches to provide builtins for

To match xlc behaviour and definition in the PowerPC ISA3.1,
it is a better idea to have ibm-clang produce an error when a

XL provides functions __vec_ldrmb/__vec_strmb for loading/storing a
sequence of 1 to 16 bytes in big endian order, right justified in the
vector register (regardless of target endianness).
This is equivalent to vec_xl_len_r/vec_xst_len_r which are only
available on Power9.
This patch simply uses the Power9 functions when compiled for Power9,
but provides a more general implementation for Power8.

This patch adds support for the next-generation arch14
CPU architecture to the SystemZ backend.
This includes:
- Basic support for the new processor and its features.
- Detection of arch14 as host processor.
- Assembler/disassembler support for new instructions.
- New LLVM intrinsics for certain new instructions.
- Support for low-level builtins mapped to new LLVM intrinsics.
- New high-level intrinsics in vecintrin.h.
- Indicate support by defining __VEC__ == 10304.
Note: No currently available Z system supports the arch14
architecture. Once new systems become available, the
official system name will be added as supported -march name.

According to https://godbolt.org/z/q5rME1naY and acle, we found that
there are different SVE conversion behaviours between clang and gcc. It turns
out that llvm does not handle SVE predicates width properly.
This patch 1) checks SVE predicates width rightly with svbool_t type.
2) removes warning on svbool_t VLST <-> VLAT/GNUT conversion.
3) disables VLST <-> VLAT/GNUT conversion between SVE vectors and predicates
due to different width.
