Explanation: Cap alignment of spills to dynamic retcon coro frame.
Scope: Affects dynamic retcon once coroutines only.
Issue: rdar://148782254
Original PR: #10449
Risk: Low, only affects the dynamic retcon once coro ABI which is only used by swift's coroutine accessors feature.
Testing: Added test.
Reviewer: Arnold Schwaighofer ( @aschwaighofer )

Apply to dynamic retcon coroutines the machinery added in
2937f8d for async coroutines.

And test aligning of allocas with large alignments.
