Log:

	* config/i386/i386.c (ix86_expand_fp_absneg_operator): When SSE
	isn't available, directly generate the simpler x87 patterns without
	the (use (const_int 0)).
	* config/i386/i386.md (*negsf2_1): Enable pre-reload if the SSE
	implementation isn't available.
	(*negdf2_1): Likewise.
	(*negxf2_1): XF mode negation is always done using the x87.
	(*abssf2_1, *absdf2_1, *absxf2_1): Likewise^3 for fabs.

	* gcc.target/i386/387-11.c: New test case.
