Thanks for taking a look!

This new patch makes a `getCurContextVersion` (now `getVersionForDecl`) take a parameter, which is the declaration that needs to be considered. This is so that we can later reuse it to check for @available(...) violations, which will be diagnosed after Sema leaves the context of the declaration we are checking. Does this still LG?
