683decd4ae Make --trace-deopt --code-comments print the Lithium instruction that caused deoptimization. 
This saves us from manually searching the disassembled code for the bailout id
when looking for the reason for deoptimization.

1311b8f0e2 Improve Hydrogen code for accessing undefined/null/Infinity. 
In some special (but probably very common) cases we can do better than loading
from a global cell for these global properties by emitting the corresponding
constant directly. This opens up opportunities for further improvements, coming
in a separate CL...

bfd048173f Notify collector about lazily deoptimized code objects. 
All slots that were recorded on these objects during incremental marking should be ignored as they are no longer valid.

To filter such invalidated slots out during slots buffers iteration we set all markbits under the invalidated code object to 1 after the code space was swept and before slots buffers are processed.

Unfortunately, callable types no longer form a range now. However, there
are only two anyway. We put them at either end of the range of JS object
types so that certain compares can be combined.

The preparser has been out of sync with the parser. As a reminder, we have the
following grammer for harmony mode

 Block ::

 SourceElement ::
   Statement
   FunctionDeclaration
   LetDeclaration

instead of

 Block ::
   { Statement* }
 SourceElement ::
   Statement

The extension to allow FunctionDeclarations in statement positions in
non-strict code is still active.

This prevents potential misuse of SeqString::kHeaderSize as in the

the computed size of all strings was off by two pointers slots.

867bb733af Remove incorrect debug-code assertion. 
We should not use slot address to find out the page. This does not work for large pages.

Also this assertion is not always true (violated during incremental marking).

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)
