This should fix r239866 for AIX.  I missed two patterns that refer to LR
as "register_operand" "l" instead of as reg:P LR_REGNO.

David, could you please test if this fixes the problem for you?

Bootstrapped and regression checked on powerpc64-linux -m32,-m64, for
what that is worth :-)

	* config/rs6000/rs6000.md
	(define_insn "*return_and_restore_fpregs_aix_<mode>_r11"): Delete
	the use of the link register.
	(define_insn "*return_and_restore_fpregs_aix_<mode>_r1"): Ditto.
