Summary:
This removes the need to coerce UnknownABI to the default ABI (O32 for
MIPS32, N64 for MIPS64 [*]) in both MipsSubtarget and MipsAsmParser.
Clang has been updated to disable both possible default ABI's before enabling
the ABI it intends to use.
[*] N64 being the default for MIPS64 is not actually correct.
However N32 is not fully implemented/tested yet.
