rs6000: Use LR_REGNO directly in the save/restore patterns 

Various patterns use "register_operand" "l" (or "=l") although those
patterns are only created refering to LR_REGNO directly.  This patch
changes those patterns to use the hard regs as well.

	*restore_gpregs_<mode>_r12, *restore_gpregs_<mode>_r1,

	*return_and_restore_fpregs_<mode>_r11,
	*return_and_restore_fpregs_<mode>_r12,
	*return_and_restore_fpregs_<mode>_r1): Use the hard register LR_REGNO
	directly instead of via the "l" constraint.  Renumber operands.
	Fix whitespace.
