[PATCH] D20878: [Coverage] Do not push a new region after a CXXTryStmt

[Igor Kudrin via cfe-commits]

I agree that it'd be expensive to put a new counter after each function call. Even if there is no `throw` statement within a TU, called functions still may raise exceptions.
Anyway, if we come across a `try` statement, we can guess that some exceptions are expected and do our best to support constructions like this:

  try {
    ...
  }
  catch (...) {
    ...
    throw;
  }
