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.
