The role of `.Pop()` on `lfbt = this->Backtrace.Pop()` is not clear.
I was not able to produce a RunCMake.Syntax test failure by removing it.

The clean-up-Parser topic currently strips the backtrace lines and some
other context from some expected test output even though the lines still
appear, such as in

  Tests/RunCMake/Syntax/UnterminatedBracket0-stderr.txt

and I think a few others.  Please restore the context lines where possible.

Overall I like the cleanup though.

Thanks,
