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.

'Let's inside a 'with' would initialize the variable
using the StoreContextSlot runtime function which

b625ce2b6b Fix a bug in scope analysis. 
When recompiling code (e.g., when optimizing) we could incorrectly hoist
some function expressions.  This leads to incorrect results or a crash.  The
root cause was that functions were not correctly categorized as expression
or declaration at parse time.

This requires some extra hoops to prevent the print name "anonymous" for
functions created by 'new Function' from establishing a binding.

9721eddc1f Ensure that the length property of bound functions are actual unique 
for the individually bound functions.

Our existing code will generate a new function on every call to bind,
but it will use the same shared function. When setting the lenght this
will be set on the shared function, i.e., the length of all bound
functions will be that of the last bound function.

ffa08197e4 tighten invariants of HValue::InferRange 
* src/hydrogen-instructions.cc (HValue::InferRange): Only mark values
  with int32 representation as never being -0.  Always return a non-NULL
  value; callers should check for representation().IsNone() if that's
  their concern.

  In practice these invariants were not violated by callers, but they
  were sometimes two calls away, which seems brittle.

4487f8c050 Revert "Revert "Fix a bug in scope analysis."" 
Reapply r8783 with an additional fix.

Because the preparser and parser do not use the same scope analysis to
determine if a function can be lazily compiled, the parser can have false
positives.  Rather than treating this as a parse error, treat the preparser
as authoritative and eagerly compile the function.
