As a result of the previous changes, epilogue_insns pattern can only be generated in Thumb1.

As a result of the previous changes, epilogue_insns pattern can only be
generated in Thumb1. After removing other cases in define_insn for
epilogue_insns, the function arm_output_epilogue becomes dead code and can
be eliminated, along with all its helper functions.
