This patch adds new define_insn patterns for epilogue with integer
registers.
The patterns can handle pop multiple with writeback and return (loading into
PC directly).
To handle return, the patterns use a new special predicate
pop_multiple_return, that uses ldm_stm_operation_p function from a previous
patch. To output assembly, the patterns use a new function
arm_output_multireg_pop.
This patch also adds a new function arm_emit_multi_reg_pop
that emits RTL that matches the new pop patterns for integer registers.
This is a helper function for epilogue expansion. It is used by a later
patch.
