re PR target/36064 (could not split insn with -O1 -march=nocona -m32)

	PR target/36064
	* config/i386/i386.md (floatdi<X87MODEF:mode>2_i387_with_xmm splitters):
	Use match_scratch instead of match_operand for operands 3 and 4.

testsuite/ChangeLog:

	PR target/36064
	* gcc.target/i386/pr36064.c: New test.
