commit ecc81e33123d7ac9c11742161e128858d844b99d

Add direct support for Linux kernel __fentry__ patching
emitted a label, 1, for __mcount_loc section:
1: call mcount
.section __mcount_loc, "a",@progbits
.quad 1b
.previous
If __mcount_loc wasn't used, we got an unused label. Update
x86_function_profiler to emit label only when __mcount_loc section
is used.
