Encapsulate the helper functions in mjsunit.js.
Now only exposes the exception class and the assertXXX functions.
Make assertEquals use === instead of ==.
This prevents a lot of possiblefalse positives in tests, and avoids
having to do assertTrue(expected === actual) when you need it.
Fixed some tests that were either buggy or assuming == test.

Allows backtracking to clear registers instead of pushing and popping
them to restore state.
Redo of 1135 with bug fixed.

Reduces number of pushes when flushing a trace. Some are converted to clears
in the undo-code instead, and some just ignored if they have no value worth restoring.
