65bf05a4 - [Instrumentation][nsan] Intrinsic tests + bugfixes (#186803)

[Instrumentation][nsan] Intrinsic tests + bugfixes (#186803) Add comprehensive lit-test coverage to the NumericalStabilitySanitizer's intrinsic and libfunc handling. Also, several minor bugfixes: - Fix typo in llvm.nearbyint.f80's name. - Remove lround and llround intrinsics, since they return ints (and are not instrumented by nsan as a result). - Fix fmuladd.f64 intrinsic to map to fmuladd instead of fma. - Add missing fmuladd.f80 variant.
