[PATCH 1/3][rs6000] x86-compat vector intrinsics fixes for BE, 32bit

- Subject: [PATCH 1/3][rs6000] x86-compat vector intrinsics fixes for BE, 32bit
Fix general endian and 32-bit mode issues found in the
compatibility implementations of the x86 vector intrinsics when running the
associated test suite tests. (The tests had been inadvertently made to PASS
without actually running the test code. A later patch fixes this issue.)
In a few cases, the opportunity was taken to update the vector API used in
the implementations to the preferred functions from the
OpenPOWER 64-Bit ELF V2 ABI Specification.
