Justin Lebar e3fb38059f [TM] Restore default TargetOptions in TargetMachine::resetTargetOptions. ... Summary: Previously if you had * a function with the fast-math-enabled attr, followed by * a function without the fast-math attr, the second function would inherit the first function's fast-math-ness. This means that mixing fast-math and non-fast-math functions in a module was completely broken unless you explicitly annotated every non-fast-math function with "unsafe-fp-math"="false". This appears to have been broken since r176986 (March 2013), when the resetTargetOptions function was introduced. This patch tests the correct behavior as best we can. I don't think I can test FPDenormalMode and NoTrappingFPMath, because they aren't used in any backends during function lowering. Surprisingly, I also can't find any uses at all of LessPreciseFPMAD affecting generated code. The NVPTX/fast-math.ll test changes are an expected result of fixing this bug. When FMA is disabled, we emit add as "add.rn.f32", which prevents fma combining. Before this patch, fast-math was enabled in all functions following the one which explicitly enabled it on itself, so we were emitting plain "add.f32" where we should have generated "add.rn.f32".
