rs6000: Add support for compatibility built-ins
The LLVM and GCC teams agreed to rename the __builtin_mma_assemble_pair and
__builtin_mma_disassemble_pair built-ins to __builtin_vsx_assemble_pair and
__builtin_vsx_disassemble_pair respectively. It's too late to remove the
old names, so this patch renames the built-ins to the new names and then
adds support for creating compatibility built-ins (ie, multiple built-in
functions generate the same code) and then creates compatibility built-ins
using the old names.
