[PATCH] Permit use of AIX Vector extended ABI mode

AIX only permits use of Altivec VSRs 20-31 in a Vector Extended ABI mode. This patch explicitly enables use of the VSRs using the new -mabi=vec-extabi command line option also implemented in LLVM for AIX. Bootstrapped on powerpc-ibm-aix7.2.3.0 and powerpc64le-linux-gnu. gcc/Ch
