Jordan Rose 4cdac3fc4c Don't add variables declared in 'guard let' to a SourceFile's Decls. ...

These variables really are local variables -- they have have a
TopLevelCodeDecl as their DeclContext rather than the SourceFile.
Treating them as global variables caused crashes in serialization.

We need an overhaul of top-level variables in script files anyway
(see rdar://problem/20992489&21628526), but this fixes the immediate
issue.
