ewah: implement bitmap_or()

We have a function to bitwise-OR an ewah into an uncompressed bitmap,
but not to OR two uncompressed bitmaps. Let's add it.

Interestingly, we have a public header declaration going back to
e1273106f6 (ewah: compressed bitmap implementation, 2013-11-14), but the
function was never implemented. That was all OK since there were no
users of 'bitmap_or()', but a first caller will be added in a couple of
patches.
