Check for interrupts and stack overflow in TParserGet(). TParserGet() recurses for some token types, meaning it's possible to drive it to stack overflow. Since this is a minority behavior, I chose to add the check_stack_depth() call to the two places that recurse rather than doing it during every single call.
While at it, add CHECK_FOR_INTERRUPTS(), because this can run unpleasantly long for long inputs. Per bug #17995 from Zuming Jiang. This is old, so back-patch to all supported branches.
