[Driver] Verify -mrecord-mcount in Driver, instead of CodeGen after D71627
GCC's x86 and s390 ports support -mrecord-mcount. Other ports reject the
option.
aarch64-linux-gnu-gcc: error: unrecognized command line option ‘-mrecord-mcount’
Allowing this option can cause failures when building Linux kernel for
aarch64, powerpc64, etc, which will think the feature is available if
the clang command returns 0.
