e8ffc2bebd Make the speed of incremental marking depend also on the rate 
at which we are hitting expensive write barrier operations,
not just on the rate of allocation.

3018b875b1 Integrate map marking into static marking visitor. 
This refactors the specialized marking of map contents to be done by the
static marking visitor shared between full and incremental marking. This
also fixes an issue where some maps weren't accounted for in the object
stats tracker. But more importantly, it simplifies the code base.

white objects when compacting.  Add flag for incremental code
compaction.

f9b93e6cc7 Implement map collection for incremental marking. 
This causes map transitions to be treated weakly during incremental
marking and hence allows clearing of non-live transitions. The marking
code is now shared between incremental and non-incremental mode.

cd8d915c72 Clean up the marking speed heuristics. This reduces the 
max heap size on 64 bit from ca. 300Mbytes to ca. 200Mbytes
on Ulan's splay variant.  On 32 bit not much change.

610281f4ee Fix calculation of live-bytes in pages. 
The "live bytes" count is *really* a "marked black" count - i.e., the count of bytes *known* to be live.

Fix aggravating bug on X64 where assembler code used a value that was off
by a factor of 2^31.

Ensure that sweeping clears live-bytes. Added other missing increments.

Added print statements to trace live-byte modifications, under a flag.

Still a few cases of undercounting left.

(New issue to merge from GC branch to bleeding_edge)
