Otherwise, it's never initialized. This doesn't affect normal compilation
because it doensn't reach only-user SILGen due to typecheck error. However,
IDE refactoring uses this regardless of the error.

This is immensely useful when working on generic code, where the signatures
of (many) functions are all that is required, and removing the bodies makes
things compile faster, allows tools like creduce to work better and results in
less noise in a debugger.
Unfortunately the design of refactoring means this currently only works on a
single top-level decl, or multiple decls inside a type.
This converts the instances of the pattern for which we have a proper
substitution in lit. This will make it easier to replace it
appropriately with Windows equivalents.
Some of the implicit decls generated for lazy vars have invalid source ranges.
For now, just always walk into implicit decls when looking for name locations.
Resolves rdar://problem/35255644.
Adds support for renaming subscripts with external names, e.g.
subscript(x y: Int), and introduces a noncollapsible parameter name range for
subscript parameters, since these shouldn't be collapsed with an argument label
of the same name as function parameter names are.
