Gor Nishanov 04491bd8f3 [coroutines] Promote cleanup.dest.slot allocas to registers to avoid storing it in the coroutine frame 
Summary:
We don't want to store cleanup dest slot saved into the coroutine frame (as some of the cleanup code may
access them after coroutine frame destroyed).

This is an alternative to https://reviews.llvm.org/D37093

It is possible to do this for all functions, but, cursory check showed that in -O0, we get slightly longer function (by 1-3 instructions), thus, we are only limiting cleanup.dest.slot elimination to coroutines.
