This speeds up the check by ~10x.

This was tested by writing a simple test that compares a for-loop and
array.every():

for (var i = 0; i < kMemSize; i++) {
      assertEquals(0, array[i]);
}

assertTrue(array.every((e => e == 0)));

The for-loop takes ~180s, every() takes ~19s.

Numbers above are for arm.debug build (simulator). On x64.debug builds
we can see a similar 10x improvement, from ~6s to ~400ms.
