On i686-linux this new testcase FAILs with:
cc1: warning: SSE instruction set disabled, using 387 arithmetics
FAIL: gcc.target/i386/pr104188.c (test for excess errors)
Excess errors:
cc1: warning: SSE instruction set disabled, using 387 arithmetics
This is because it uses -mfpmath=sse, but -msse2 isn't on. Fixed
by adding -msse2 to dg-options and requiring sse2_runtime effective
target.
Tested on x86_64-linux and i686-linux, committed as obvious to trunk/11:

* gcc.target/i386/pr104188.c: Add dg-require-effective-target
sse2_runtime. Add -msse2 to dg-options.
