Fangrui Song 4cb0dafe51 [gcov] Set nounwind and respect module flags metadata "frame-pointer" & "uwtable" for synthesized functions ... This applies the D100251 mechanism to the gcov instrumentation pass. With this patch, `-fno-omit-frame-pointer` in `clang -fprofile-arcs -O1 -fno-omit-frame-pointer` will be respected for synthesized `__llvm_gcov_writeout,__llvm_gcov_reset,__llvm_gcov_init` functions: the frame pointer will be kept (note: on many targets -O1 eliminates the frame pointer by default). `clang -fno-exceptions -fno-asynchronous-unwind-tables -g -fprofile-arcs` will produce .debug_frame instead of .eh_frame.
