This patch is need to fix:
FAIL: gcc.target/i386/pr67985-3.c scan-assembler movd[ \t]%xmm[0-7], %eax
FAIL: gcc.target/i386/pr67985-3.c scan-assembler mulss
OK for trunk?
Thanks.

Subject: [PATCH] i386: Adjust gcc.target/i386/pr67985-3.c
Since -march=lakemont turns off 80387 and SSE,
-miamcu -mfpmath=sse -march=lakemont
results in -mfpmath=387, __attribute__((target("arch=haswell"))) doesn't
enable SSE FP math. SSE shouldn't be used for FP math in pr67985-3.c.

* gcc.target/i386/pr67985-3.c: Update.
