Make the static enforcement of accesses in noescape closures stored-property
sensitive. This will relax the existing enforcement so that the following is
not diagnosed:
struct MyStruct {
var x = X()
var y = Y()
mutating
func foo() {
x.mutatesAndTakesClosure() {
_ = y.read() // no-warning
}
}
}
To do this, update the access summary analysis to summarize accesses to
subpaths of a capture.
