Summary:
Two exceptions to this:
test/CodeGen/Mips/octeon.ll
test/CodeGen/Mips/octeon_popcnt.ll
these test extensions to MIPS64
One test is altered for MIPS-IV:
test/CodeGen/Mips/mips64countleading.ll
Tests dclo/dclz which were added in MIPS64. The MIPS-IV version tests
that dclo/dclz are not emitted.
Four tests fail and are not in this patch:
test/CodeGen/Mips/abicalls.ll
test/CodeGen/Mips/fcopysign-f32-f64.ll
test/CodeGen/Mips/fcopysign.ll
test/CodeGen/Mips/stack-alignment.ll
Depends on D3343
