While brk[ab] zeroing has a flags setting option, the merging variant
does not. Retain the same argument structure, to share expansion but
force the flag zero and do not decode bit 22.

The xml from which Alex and I extracted risu test cases does not call
out bit 22 as a field, so we did not test this illegal encoding.
