Andrew Trick 32baaf7876 Add SILGenCleanup::completeOSSLifetimes ...

Presently under -enable-ossa-complete-lifetimes.

This allows SILGen to skip OSSA cleanups, for example at dead-end
blocks.

Long term, we may remove OSSA cleanups from SILGen entirely (except
for lexical borrow scopes). This changes lets us experiment with that
option.
