The test gcc.dg/tree-ssa/pow_fold_1.c was failing for 32-bit x86 due to incompatibility of '-fexcess-precision=16' with '-mfpmath=387'. In order to resolve this, this patch adds -msse -mfpmath=sse+387 for i?86-*-*.
We tested this by running the test on an x86_64 machine with
--target_board={unix/-m32}.
OK for mainline?
