If this test does not use SIMDs then this flag should not be needed. If the test
nevertheless fails without setting the flag, then that's a (serious) bug. You
are probably missing places where you need to make code paths dependent on the
flag.

I don't understand the comment. This test does add a test for SIMD.float32x4,
below. Do you think I should remove this test, or make it conditional on SIMD
being defined?

Ah, sorry, I somehow got lost in the diffs. Please ignore this comment and the
other one. :)
