74ef753067 Change inlined cache of intanceof stub to use indirection through cell.
The stub was directly patching caller's code without issuing write barrier which violated incremental marking invariants.

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.

858320725b Split incremental marking write barrier into fast and slow paths.
Force inlining of the fast path.

Force inlining LiteralBuffer::AddChar and Scanner::AddLiteralChar.

e8a26d1eb1 Add write barrier helper for code patching and refactor stack check patching.
The new helper avoids expensive FindCodeForInnerPointer invocation when we have
the host code object available. It is used when patching stack checks.

Also some comments on the ARM platform are corrected.

554a12fbbc Fix free list node ending up on evacuation candidate.
This is a temporary fix which avoids compaction when incremental marking
is restarted during an old-space-step. That could turn the page that
holds the chosen free list node into an evacuation candidate. It could
also cause several other inconsistencies if it happens during scavenge.

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)
