Hi!
The following patch adjusts the pr49095.c testcase, so that it counts only
the loads through the first argument of the function and thus doesn't care
how many spill/fills are done using stack saves/loads vs. pushes.
Regtested on x86_64-linux and i686-linux, ok for trunk?

* gcc.target/i386/pr49095.c: Include in scan-assembler-times patterns
the first argument register, so that occassional spills/fills are
ignored.
