Because of LocalHeap safepoints, our existing assert scopes don't
necessarily maintain the same guarantees as desired. In particular,
DisallowHeapAllocation no longer guarantees that objects don't move.
This patch transitions DisallowHeapAllocation to
DisallowGarbageCollection, to ensure that code using this scope is
also protected against safepoints.

This removes the dependency on Lua for running gcmole, and Python's
expressiveness lets us clean up the code a bit, including getting rid
of global variables, embedding the multiprocessing (removing the need
for a separate `parallel.py`), and using difflib for printing the test
expectation diff.
