Optimize [0 = x & MASK] in range-ops.

Optimize [0 = x & MASK] in range-ops.

For [0 = x & MASK], we can determine that x is ~MASK.  This is
something we're picking up in DOM thanks to maybe_set_nonzero_bits,
but is something we should handle natively.

This is a good example of how much easier to maintain the range-ops
entries are versus the ad-hoc pattern matching stuff we had to do
before.  For the curious, compare the changes to range-op here,
versus maybe_set_nonzero_bits.

I'm leaving the call to maybe_set_nonzero_bits until I can properly
audit it to make sure we're catching it all in range-ops.  It won't
hurt, since both set_range_info() and set_nonzero_bits() are
intersect operations, so we'll never lose information if we do both.
