Qiu Chaofan	2866c6cad4	[NFC] [PowerPC] Narrow fast-math flags in tests ... A lot of tests under PowerPC are using fast flag, while fast is just alias of 7 fast-math flags. This change makes test points clearer. mc-instrlat.ll and sms-iterator.ll keeps unchanged since they are not testing fast-math behavior. (one for machine combiner crash, one for machine pipeliner bug) Reviewed By: steven.zhang, spatel Differential Revision: https://reviews.llvm.org/D78989	2020-05-13 17:22:45 +08:00
