Currently, compiling a program with the `-pg` flag will result in an undefined symbol error for `.mcount`. This revision fixes the call to use `__mcount`, which requires a pointer argument to a pointer-sized object (unique per inserted call) on AIX. This is only a partial fix. This patch should fix the `-pg` flag's behaviour on AIX to work with code you are compiling, but it will not link against standard libraries with `mcount` instrumentation calls. The next step is to add profiled libraries to the linker search paths in the Clang driver for the AIX toolchain when linking with `-pg`. Differential Review: https://reviews.llvm.org/D135384
