Arnold Schwaighofer	f82dbef1b7	Add a ClosureLifetimeFixup pass ... To replace the code in DI and eventually remove PostponedCleanup in a follow-up. When SILGen emits ``convert_escape_to_noescape [not_guaranteed] %operand`` instructions it assumes that a later SIL pass (this pass) comes along and inserts retain_value/release_value instructions such that the lifetime of the operand for the duration of the trivial closure result. This commit introduces the pass but does not yet use it.	2018-04-13 13:25:07 -07:00
