f09dfc93a9 Swift SIL: escape effects for function arguments. 
Store a list of argument effects in a function, which specify if and how arguments escape.
Such effects can be specified in the Swift source code (for details see docs/ReferenceGuides/UnderscoredAttributes.md) or derived in an optimization pass.

For details see the documentation in SwiftCompilerSources/Sources/SIL/Effects.swift.

383c52aa35 SIL: rename dealloc_ref [stack] -> dealloc_stack_ref 
Introduce a new instruction `dealloc_stack_ref ` and remove the `stack` flag from `dealloc_ref`.

The `dealloc_ref [stack]` was confusing, because all it does is to mark the deallocation of the stack space for a stack promoted object.
