re PR bootstrap/56656 (Suffix or operands invalid for 'movq')

	PR bootstrap/56656
	* configure.ac (HAVE_AS_IX86_INTERUNIT_MOVQ): New test.
	* configure: Regenerate.
	* config.in: Regenerate.
	* config/i386/i386.md (*movdf_internal): Use
	HAVE_AS_IX86_INTERUNIT_MOVQ to handle broken assemblers that require
	movd instead of movq mnemonic for interunit moves.
	(*movdi_internal): Ditto.
