@NoEscape

- @NoEscape functions are trivial types That makes @NoEscape functions incompatible with escaping functions. - Forward ownership of mark_dependence %3 : callee_guaranteed () -> () on %0 : noescape @callee_guaranteed () -> () - SIL: Add ABIEscapeToNoEscapeConversion to SILFunctionType::ABICompatibilityCheckResult - SIL: A thin_to_thick_function with a @NoEscape result type has trivial ownership - SIL: thin_to_thick_function can create noescape function types Part of: SR-5441 rdar://36116691

@NoEscape

- make @NoEscape function types trivial - think_to_thick_function with @NoEscape result type - Fix for getSwiftFunctionPointerCallee Part of: SR-5441 rdar://36116691

@NoEscape

- Emit a withoutActuallyEscapingClosure partial apply This is to convert an @NoEscape closure to an escaping closure. This needs to be done in preparation of @NoEscape closure contexts becoming trivial. - Insert escaping to noescape conversions - Fix SILGen for @NoEscape - Postpone closure cleanups to outside the argument scope - Apply postponement recursively for closures passed to subscripts - Only skip applying escapeness conversions for Swift thick functions - Fix parameter convention for noescape closures in thunks Part of: SR-5441 rdar://36116691

…cape

… of partial_apply

We should not need those -- except (at least) for functions passed as arguments to materializeForSet ...

…scape casts

- also combine thin_to_thick_function and convert_escape_to_noescape

It can't be moved because there are pointers to it

The benchmark run for the simply_cfg addition is here: https://ci.swift.org/view/Pull%20Request/job/swift-PR-osx-perf/138/

We can treat a throw instruction like we would a return. Insert the release for the propagated partial_apply before the throw instruction.
