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.
