i386.c: Change GET_CODE (...) == CONST_DOUBLE check to CONST_DOUBLE_P predicate.

Browse Source 
* config/i386/i386.c: Change GET_CODE (...) == CONST_DOUBLE check
	to CONST_DOUBLE_P predicate.
	(standard_sse_constant_p): Return 0 for !TARGET_SSE.
	(ix86_legitimate_constant_p) <case CONST_WIDE_INT>: For 32bit targets,
	allow only operands that satisfy standard_sse_constant_p predicate.
	* config/i386/i386.md: Change GET_CODE (...) == CONST_DOUBLE check
	to CONST_DOUBLE_P predicate.
