gcc8-pr81121.patch
Untested fix. The old splitter had also && TARGET_SSE_MATH, dunno if we want
to readd that too or not. But && TARGET_SSE2 is certainly needed, the fact
that output satisfies sse_reg_operand doesn't mean TARGET_SSE2 is enabled, and
we need it for the instructions used in the splitter.
