Currently not crankshaft support, using flag on non-ia32 platforms will lead to write barrier misses and crashes.

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.

(New issue to merge from GC branch to bleeding_edge)

81df4a42e4 Support for precise stepping in functions compiled before debugging was started (step 1) 
This change will ensure that all non-optimized code will be compiled
with debug break slots when debugging is initiated. This is handled by
scanning the heap for non-optimized functions without debug break slots and setting their code to be lazy recomplied. When the lazy recompilation happens the code will ge generated with debug break slots (if debugging is still active at that point in time).

2c8680cc46 Avoid size increase of snapshot. 
The prototype of builtin functions is already unwritable, so we don't
have to make it so (the default map for functions changes after builtins
are initialized).

We no longer need to make the prototype non-extensible, since all properties
that are ever read by the bultins code has been added and frozen already.
Adding properties to the prototype, or changing its __proto__, cannot affect
code.

Removing these two pieces of initialization code reduces the snapshot size
by a few Kb.

07c1c9ebc7 MIPS: small test-case fix for chaining of fixup position. 
Add nops to the branch-delay slots of the 'beq' and 'bne' instructions
used in the test-case. Having a branch instruction in the branch-delay-slot
of another branch is undefined on mips.

In regular code we avoid this by using the Branch() macro-instruction which
fills the branch-delay-slot with nop() automatically, unless the programmer
asks to use it (via USE_BRANCH_DELAY).

There is more info about branch-delay-slots on this page, and in the ISA
reference also on the page:

The ARM and MIPS assemblers had a bug where they did not handle the last element
in the list of code positions correctly during the fixup of offsets for forward
jumps. This happened when the first instruction contained a forward jump to a
label, and that label was used in a forward jump later, too.

Unified the code for Assembler::next on ARM and MIPS while we were there.

Added test cases, even for ia32/x64, which seem to be correct, even I don't
fully understand why... %-}

dda2889ba1 Refactor .gyp files: 
common.gypi now contains global target defaults and is included by all .gyp files;
standalone.gypi contains definitions for stand-alone v8 builds.
This fixes d8 for the ARM simulator.

TEST=compiles and tests pass on all platforms

2f2f90610e Changed computation of func.caller to skip some built-in functions. 
Now skips built-in functions called from other built-in functions,
so only the initally called built-in function is exposed.

13dd915a2a Fix typo in assert. 
Also remove the requirement to have an AssertNoAllocation object when getting the flat content. We actually do allow allocation, it's just GC's we don't allow.

9eb7d4a53c Replace ToAsciiVector and ToUC16Vector with single function that returns a tagged value. 
The tag tells whether the content is ASCII or UC16, or even if the string wasn't flat.
