Slava Pestov a6a96da558 AST: Source range of FuncDecl/ConstructorDecl should include the thrown type ...

When a function declaration has a body, its source range ends at the
closing curly brace, so it includes the `throws(E)`. However, a
protocol requirement doesn't have a body, and due to an oversight,
getSourceRange() was never updated to include the extra tokens
that appear after `throws` when the function declares a thrown
error type. As a result, unqualified lookup would fail to find a
generic parameter type, if that happened to be the thrown type.

Fixes rdar://problem/143950572.
