Matthew Flatt 584920b3a6 GC: clarify page field overloadings
Rename fields in a page record and split some of them with `union` to
better document the intent of each field.

This change is intended to have no effect on the GC's behavior. One
tricky case is the line dropped around line 3542 of "newgc.c". That
line reset `scan_boundary` (formerly `previous_size`), which on the
surface is inconsistent with leving objects before the boundary
without `marked` bits set. However, that line is reachable only
when geneation-1 objects are being marked (objects newly moved
there would not be unmarked), in which case `san_boundary` should
already be reset.
