TestLeakAutoVar: Split recursiveCountLimit test to separate class (#2995)
This test is by far the slowest one to run. Split it to a separate class
to make it easy to select if it should be run during development.

remove cleanupAfterSimplify from the template simplifier (#2998)
The template simplifier works well enough now so cleanupAfterSimplify is
no longer necessary.  In fact cleanupAfterSimplify was introducing a bug
which improperly simplified C++ style casts.

Bugs should be exposed and fixed properly rather than just hiding them.
