The particular version of the GNU assembler that I'm using doesn't
accept an alignment argument to .lcomm. It does accept an alignment
argument to .comm, but this is a number of bytes rather than a number of
address bits.

suggests that the third argument to .comm (and perhaps, by analogy, the
third argument to .lcomm) is always a number of bytes. So
COMMDirectiveAlignmentIsInBytes might not be needed.
