optabs.c (expand_fix): Look for wider integer modes first.

	* optabs.c (expand_fix): Look for wider integer modes first.

	* i386.md (mov?f): Avoid the fake const double trick for medium
	memory model.
	(min?f*/max?f*): Prohibit memory operands for i387 variant.
	(fop_df_4): Disable for SSE compilation.
