Hmm looking at `HWAddressSanitizer::getShadowNonTls` this does actually need to
be an integer converted to a pointer, so it needs to be zero even if null
pointers are all ones. The commit message says it's there to avoid
rematerializing constants, so maybe it could be omitted for the zero case but I
am not too familiar with this code (@pcc).
