[committed] Fix gcc.target/i386/pr87955.c testcase

[Jakub Jelinek]

Hi!

The testcase doesn't emit expected diagnostics on i?86, because the default
is -mfpmath=387 there and so the function is perfectly inlinable.

The following patch makes sure we compile the testcase with -msse2 -mfpmath=sse
everywhere, so it succeeds (or FAILs with the ipa-inline.c change reverted)
on all x86 configurations the same.

Tested on x86_64-linux, committed to trunk as obvious.
