[cfe-dev] Retrieving assignment operator from AST

[George Burgess IV via cfe-dev]

Readding cfe-dev.

I'm not at all familiar with the Rewriter APIs, so I could be wrong, but
ISTM that `Rewriter::InsertTextAfter(Loc, Str)` will insert text *at* Loc
(after any other text that was previously inserted at Loc). It also looks
like `bo->getLocEnd()` will not return the location of ";" in "foo = bar;".
So, it makes sense that things end up a bit off.

Have you tried using `InsertTextAfterToken` instead? It looks like that may
do what you want.
