re PR target/47369 ([x32] internal compiler error: in extract_insn, at recog.c:2109)

	PR target/47369
	PR target/49853
	* config/i386/i386.c (ix86_expand_move): Call convert_to_mode
	if legitimize_tls_address returned operand in wrong mode. Allow
	SImode and DImode symbolic operand for PIC.  Call convert_to_mode
	if legitimize_pic_address returned operand in wrong mode.
