MIPS floating-point comparisons are sometimes improved, sometimes pessimized.
Here are the tests that are pessimized more:
gcc.c-torture/execute/ieee/compare-fp-1.c
gcc.c-torture/execute/ieee/compare-fp-4.c (-fno-trapping-math)
gcc.c-torture/unsorted/DFcmp.c
(not for all versions, but for example at -O1 -mfp32 -mgp32 they are affected).
Just removing these three is enough to change from a depressing

This bug needs TLC from a MIPS person. At least a confirmation would be nice.

Unconfirmed -> P3. Also mips-linux isn't primary nor secondary - unclear if
this bug also applies to mipsisa64-elf.

Nobody cares. Dropping to P4 based on mips-linux status.
