[mips] The default ABI depends on the CPU not the Arch on MTI and IMG vendor triples.
Summary:
32-bit CPU's default to O32. 64-bit CPU's default to N64. The default CPU
(mips32r2/mips64r2) still depends on the arch so there's no functional
change when the CPU isn't specified but commands like:
clang -target mips-mti-linux-gnu -mips64r2
will now default to a 64-bit ABI like our gcc toolchains do* instead of
asserting in the backend**.
Other vendors (including Triple::UnknownVendor) still derive the default
ABI from the arch.
* Although not the same one as our gcc toolchains, clang has historically
defaulted to N64 where gcc defaults to N32.
** Mixing O32 and a 64-bit CPU causing assertions is a long-standing bug.
