[mid-end][__RTL] Set global epilogue_completed in skip_pass
Set global epilogue_completed when skipping pro_and_epilogue pass
When compiling RTL functions marked to start at a pass after the reload
pass, `skip_pass` is used to mark the reload pass as having completed
since many patterns use the `reload_completed` variable to determine
whether to run or not.
Here we do the same for the `epilogue_completed` variable and the
pro_and_epilogue pass.
Also include a testcase that relies on the availability of a
define_split in the aarch64 backend that is conditioned on this
`epilogue_completed` variable.
regtest done on native aarch64
regtest done on native x64_86
