	* config/i386/i386.c (x86_64_reg_class_name): Re-indent.
	...
	(movsi_1): Use 'x' instead of 'Y' constraints.
	(movsi_1_nointernunit, movdi_2, movdi_1_rex64): Likewise.
	(movdi_1_rex64_nointerunit): Likewise.
	(movdf_nointeger, movdf_integer): Likewise.  Handle SSE1.       <<<
	...

There is a problem with register constraints in movdf_nointeger pattern. It
looks that 'x' should be substituted by 'Y'. Patch is in testing.
