re PR target/71097 (Additional testsuite failures with -mcmodel=medium)

	PR target/71097
	* config/i386/i386.md (*movtf_internal): Before register allocation,
	do not allow FP constants for CM_MEDIUM memory model, allow only
	standard FP constants for CM_LARGE and CM_LARGE_PIC models.
	(*movxf_internal): Ditto.
	(*movdf_internal): Ditto.
	(*movsf_internal): Ditto.
