Subject: [PATCH 08/20] Allow stacktrace variation in exception test cases

The JIT for ARM will give a more detailed stacktrace for operators
such as '+'/2 (the top stacktrace entry will be for the operator
including its arguments). Update test cases that test for exceptions
to allow for this variation.
