Reviewed by Justin Michaud.

1. Fix PingPongStackOverflowTest to handle the case where the JIT is disable.
   It should not force disable the LLInt if the JIT is not available.

2. Fix ExecutionTimeLimitTest tier options to use Options::useBaselineJIT(), instead of
   Options::useJIT(), to determine whether the baseline JIT is enabled of not.  The value
   of Options::useJIT() is determined at launch and already puts in place infrastructure
   that assumes either the JIT is enabled or not.  As a result, it should never be changed
   at runtime.  This especially impacts runs with the JITCage enabled which installs JIT
   thunks that expect JITCage conformant behavior.

3. Fix ExecutionTimeLimitTest to not run the test with JIT tiers if JIT'ing is disabled.
