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