Remove redundant `ignore-tidy-linelength` annotations This is step 2 towards fixing #77548. In the codegen and codegen-units test suites, the `//` comment markers were kept in order not to affect any source locations. This is because these tests cannot be automatically `--bless`ed. 2021-04-03 11:05:11 +00:00			`//`

Use function attribute "frame-pointer" instead of "no-frame-pointer-elim" LLVM 8 (D56351) introduced "frame-pointer". In LLVM 10 (D71863), "no-frame-pointer-elim"/"no-frame-pointer-elim-non-leaf" will be ignored. 2019-12-31 05:35:13 +00:00			`// CHECK: attributes #{{.}} "frame-pointer"="all" "instrument-function-entry-inlined"="{{.}}mcount{{.*}}"`
