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.
