Revert r304929 [mips] Add runtime options to enable/disable madd/sub.fmt
Revert r304929 since the test broke buildbots.
Original commit:
[mips] Add runtime options to enable/disable madd.fmt and msub.fmt
Add options to clang: -mmadd4 and -mno-madd4, use it to enable or disable
generation of madd.fmt and similar instructions respectively, as per GCC.
Patch by Stefan Maksimovic.
