re PR target/65593 (internal compiler error: in extract_insn, at recog.c:2343)

	PR target/65593
	* config/i386/i386.c (legitimize_pic_address): If base
	is SYMBOL_REF or LABEL_REF using %rip addressing, force
	it to reg to avoid PLUS of SYMBOL_REF/LABEL_REF and register.

	* gcc.c-torture/compile/pr65593.c: New test.
