Spur:
Round the space estimate when a new segment is used for planning compaction to
avoid an assert fail.

Add some debugging routines: forwardersIn:, indexOf:in:.

SpurImageSegments
Fix bad slip in computing objectsReachableFromRoots: (the wrong object was
being marked when pushing unmarked objects onto the objStack), and rewrite
to avoid growing the markStack unnecessarily.  Fix an assert fail in adding
to the mark stack by handling totalFreeOldSpace correctly (and comment other
callers of allocateLargestFreeChunk).

Refactor use of marked bit to identify heap objects copied into the segment
into isCopiedIntoSegment: & markAsCopiedIntoSegment:.

Make sure unsigned comparisons are used for several address/oop comparisons
in the segment code.

Slang:
Propagate types from "ible" to "var" in "var := ible := expr" when inferring
types from assignments.
