or
pointer first)

Comment:
The `BTM` flag is supposed to distinguish between the pointers-first
layout used for heap objects and the bitmap layout used for stack frames,
ie. whether `info->layout.payload` is used or `info->layout.bitmap`. The
layout of `PAP` and `AP` is a separate special case.
But you're right that it is currently (a) wrong and (b) not used, so I'll
remove it.
