Moving CompileDeepTree_NoStackOverflowFast to the outer loop

 It appears that the test equally stresses the Expression Tree Compiler and the JIT compiler.

Normally this is not a problem since JIT compiler uses much less resources that ET compiler and 128Kb of stack is more than enough to JIT the resulting method.
That does not seem to be the case when running on Debug and the test may fail on debug runtime/JIT

We generally want the inner loop to pass on Debug though, so the test should be moved to the outer loop.
