This patch series adds support for the next-generation arch13
CPU architecture to the SystemZ backend.
This includes:
- Basic support for the new processor and its features.
- Support for low-level builtins mapped to new LLVM intrinsics.
- New high-level intrinsics in vecintrin.h.
- Indicate support by defining __VEC__ == 10303.
Note: No currently available Z system supports the arch13
architecture. Once new systems become available, the
official system name will be added as supported -march name.

Summary:
These all had somewhat custom file headers with different text from the
ones I searched for previously, and so I missed them. Thanks to Hal and
Kristina and others who prompted me to fix this, and sorry it took so
long.

The following two bugs in SystemZ high-level vector intrinsics are
fixes by this patch:
- The float case of vec_insert_and_zero should generate a VLLEZF
pattern, but currently erroneously generates VLLEZLF.
- The float and double versions of vec_orc erroneously generate
and-with-complement instead of or-with-complement.
The patch also fixes a couple of typos in the associated test.

This patch updates the vecintrin.h header file to provide the new
set of high-level vector built-in functions. This matches the
updated definition implemented by other compilers for the platform,
indicated by the pre-defined macro __VEC__ == 10302.
Note that some of the new functions (notably those involving the
vector float data type) are only available with -march=z14
(indicated by __ARCH__ == 12).

This patch adds support for the System Z vector built-in functions.
The API-defined header file has the name vecintrin.h.
The user-level functions are defined in the same style as the clang
version of altivec.h, making heavy use of the __overloadable__ and
__always_inline__ attributes. Where possible the functions expand to
generic operations rather than specific built-in functions, in the hope
that that form can be optimised better.
Where a built-in routine is specified to require an immediate integer
argument, the __enable_if__ attribute is used to verify the argument is
in fact constant and in the appropriate range.
Based on a patch by Richard Sandiford.
