[ARM][cleanup] Simplify some expressions in some epilogue-related functions

Browse Source 
* config/arm/arm.c (arm_emit_multi_reg_pop): Simplify definition of
	return_in_pc.  Remove redundant assignments.
	(thumb2_emit_ldrd_pop): Simplify definition of return_in_pc.
	(arm_expand_epilogue): Don't compare boolean with true in if condition.
