	* lib/target-supports.exp (check_effective_target_mips64): New
	procedure.
	* gcc.dg/lower-subreg-1.c: Require !mips64.
	* gcc.dg/sibcall-3.c (ATTR): New macro.
	(recurser_void1, recurser_void2): Use it.
	* gcc.dg/sibcall-4.c: As for gcc.dg/sibcall-3.c.
	* gcc.dg/tree-ssa/ssa-fre-3.c: Require !mips64.
