Zarko Todorovski 2b50ce1524 [PowerPC][AIX] Enable the default AltiVec ABI on AIX 
This patch adds support for the default AltiVec ABI for AIX.

Vector registers 20 through 31 are marked as reserved and cannot
be used in the default ABI. This patch adds handling for this case
and also remove the default AltiVec ABI errors.

Zarko Todorovski be7d425edc [PPC][AIX] Add vector callee saved registers for AIX extended vector ABI 
This patch is the initial patch for support of the AIX extended vector ABI.  The extended ABI treats vector registers V20-V31 as non-volatile and we add them as callee saved registers in this patch.
