fdade92c20 Reorganize object type enum, such that proxies are no longer in the middle 
of the range of proper JS objects.

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.

41eb990afe Fix pre-parsing function declarations. 
The preparser has been out of sync with the parser. As a reminder, we have the
following grammer for harmony mode

 Block ::
   { SourceElement* }
 SourceElement ::
   Statement
   FunctionDeclaration
   LetDeclaration

instead of

 Block ::
   { Statement* }
 SourceElement ::
   Statement
   FunctionDeclaration

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

3fabe323f2 Add kHeaderSize constant to SeqString. 
This prevents potential misuse of SeqString::kHeaderSize as in the
case of live byte counting in incremental marking stub. All stubs
picked up the undefined size constant SeqString::kHeaderSize, thus
the computed size of all strings was off by two pointers slots.

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.

cf63503cad Unify the handling of comparinsons against null and undefined. 
Although this patch is not small, most parts of it are rather mechanical:

 * First of all, the concept of a 'nil-like' value is introduced, which can be
   null or undefined. They are treated symmetrically regarding comparisons, so
   it makes sense to handle them in a uniform manner. It is a mystery why
   JavaScript defines two of those beasts, when even *one* is a design wart...

 * Extended and renamed a few things which now handle undefined in addition to
   null.

 * Made the parts of the full code generator and the hydrogen generation which
   deal with comparisons a bit more similar regarding their handling of special
   cases.

 * Refactored the syntactical detection of special cases for comparisons,
   hopefully making them a bit more readable and less copy-n-paste-oriented.
   Things like this should really be a one-liner in any sane programming
   language... :-P

 * Cut down the length of the argument lists of a few functions to something
   less insane, making them more easily understandable locally. This involves
   minor code duplication, but this was a good tradeoff and can be remedied
   later if necessary.

 * Replaced some boolean arguments with more readable enums.

 * Fixed a TODO: Values which are definitely a Smi or unboxed can never be equal
   to null or undefined.

433db37747 MIPS: port Implement function proxies (except for their use as constructors). 
port r9258 (c8709a9)

Note on mips implementation: Arm reg r4 (call type) normally maps to mips
reg t0. We had already used t0 as a temp in Generate_FunctionCall() and
Generate_FunctionApply(), so I replaced that existing t0 usage with t3, and
now use t0 only for call type.

Original commit message:
Introduce new %Apply native.
Extend Execution::Call to optionally handle receiver rewriting (needed for %Apply).
Fix Function.prototype.bind for functions that have .apply modified.

Landing http://codereview.chromium.org/7891033/ for Paul Lind.
