[Jan Beulich]

This fixes some of the problems uncovered by the previously sent ix86
MMX/SSE testsuite additions.

	* config(i386/i386.c (ix86_expand_binop_builtin): Widen
conditions to
	force target and op0 to a register.
	(ix86_expand_unop_builtin): Widen conditions to force target to
a
	register.
	(ix86_expand_builtin, case IX86_BUILTIN_LOAD[HL]P[SD]): Dito.
	(ix86_expand_builtin, case IX86_BUILTIN_STORE[HL]P[SD]): Widen
	conditions to force op1 to a register.
