[cfe-dev] End location of DeclStmt

Hi Pardis,

which location does the `getEnd()` return?
I assume it's one byte to early: You can do offset-calculations with
`SourceLocation`, therefore `YourStmt->getEnd().getLocWithOffset(1)`
returns one element past the end-location.
Be careful with corner-cases as the new Location might be invalid, in a
Macro-Range (isMarcoID()) and so on. Please note, that the `DeclStmt`
might not always have a semicolon after itself.
E.g. `int my_variable = 42 /* This is my variable */;` could be such a
case. You might want to take a look 
`clang-tidy/utils/LexerUtils.{h,cpp}` as it has some functionality to
deal with such situations.

Best, Jonas
