`CodeCompletioString::getName()` was used only as the sorting keys in
`CodeCompletionContext::sortCompletionResults()` which is effectively
deprecated. There's no reason to check them in `swift-ide-test`. Instead,
check `printCodeCompletionResultFilterName()` that is actually used for
filtering.
- If a parameter type is a sugared function type, mark the type
as non-escaping by default. Previously, we were only doing this
if the parameter type was written as a function type, with no
additional sugar.
This means in the following cases, the function parameter type
is now non-escaping:
func foo(f: ((Int) -> Void))
typealias Fn = (Int) -> Void
func foo(f: Fn)
- Also, allow @escaping to be used in the above cases:
func foo(f: @escaping ((Int) -> Void))
typealias Fn = (Int) -> Void
func foo(f: @escaping Fn)
- Diagnose usages of @escaping in inappropriate locations, instead
of just ignoring them.
It is unfortunate that sometimes we end up desugaring the typealias,
but currently there are other cases where this occurs too, such as
qualified lookpu of protocol typealiases with a concrete base
type, and generic type aliases. A more general representation for
sugared types (such as an AttributedType sugared type) would allow
us to solve this in a more satisfactory manner in the future.
However at the very least this patch factors out the common code
paths and adds comments, so it shouldn't be too bad going forward.
Note that this is a source-breaking change, both because @escaping
might need to be added to parameters with a sugared function type,
and @escaping might be removed if it appears somewhere where we
do not mark function types as non-escaping by default.
Most tests were using %swift or similar substitutions, which did not
include the target triple and SDK. The driver was defaulting to the
host OS. Thus, we could not run the tests when the standard library was
not built for OS X.

optional & alias types for closure type parameters.
This allows code completion placeholder expansion to properly expand
closure parameters utilizing a typealias, e.g. dispatch_block_t.
Update and add test for the above.
