The new tests fail on 32 bit platforms, see build.webkit.org for details:

Did you mean to include this?

Yep. I exposed the JSC options to the tests to change the compilation count limits based on them.

In particular, when we use useMaximalFlushInsertionPhase, we should compile exactly 2 times in the worst case (once to discover the negative zero, then once with the right types).

Filip asked me to update the existing tests to account for FTL-eager too (will do in a follow up).
