You can rename functionFalse1 to functionFalse now that there's only one.

Ditto.  Use functionFalse.

Ditto.  Use functionFalse.

I suggest renaming "flag" to "didFTLCompile".

I suggest renaming "flag" to "didFTLCompile".

> 32-bit test failures on new tests:

the FTL is not supported on 32-bit.  Hence, these are guaranteed to fail.  We should skip these tests on 32-bit.

[Alexey Proskuryakov]

Please do skip them then!
