Darwin doesn't emit a .file directive by default
and one of the scan-asm hits for ELF targets comes from
this directive. Adjust for Darwin and explain.
Tested on x86_64-darwin16, x86_64-linux-gnu
Applied to mainline.

* gcc.target/i386/memcpy-strategy-3.c: Adjust count for Darwin and
add a comment as to the reason for the difference.
* gcc.target/i386/memset-strategy-1.c: Likewise.
