bf9b2f8c2c Heap profiler: add an ability to iterate over snapshot's nodes. 
This is a preparation for removing aggregated heap snapshots.
W/o this API, counting object instances in a snapshot is very hard.

57c1899f78 MIPS: Port some DIV changes to BinaryOpStub::GenerateInt32Stub(). 
There were some changes in ARM r8172 that we needed to port to MIPS,
but missed.

The bug was exposed with the Arm & Mips fix in r8321, "Fix wrong
parenthesis in stub ARM and MIPS generation code."

af24067fa5 Refactor the way we collect the information for associating type-related infos 
with AST IDs. Previously 3 different places had to match in how they handle a
given case, now we are down to 2, with an even simpler logic.

The downside is that due to this simpler logic the allocated dictionary could be
larger than before, but test have shown that this happens *very* rarely, because
its capacity is rounded to the next power of 2, anyway. Furthermore, the oracle
doesn't live long enough that we should really care.

The whole oracle is probably still a bit too tricky in its details, but this is
at least a step into the right direction.

8c538d9012 Made parser not accept unicode escapes inside "native" when used as a keyword. 
This is a regression relative to the original behavior, when "native" was a keyword,
since keywords cannot contain esacpes.

Added tests for escapes and for not allowing line-terminators betwen "native" and "function".

480ec43c4e Make "native" not a keyword. 
We now only recognize "native function" when it occurs in extension scripts
(parsing with a non-NULL extension), and only if there is no line-terminator
between "native" and "function" (so that it would otherwise be a Syntax Error).
Preparsing never recognizes native functions, which is acceptable since we
never preparse extension scripts (because we don't allow lazy functions
anyway).

7d527f857f Change the representation of catch contexts. 
Before, they had no extra slots and an extension object with one named
property.  Now, they use the extension slot for the property name and have
an extra slot for the thrown object.  This increases the size of the context
itself, but removes overall allocation and eliminates a level of indirection.

a4cf7be941 First steps towards better code generation for LBranch: 
* AST Expression nodes get a separate testing ID to record type info in
   ToBooleanStub later. This is necessary to avoid clashes with other uses of
   already existing IDs.

 * In order to avoid threading the condition expression through tons of places,
   TestContexts carry it now with them. Note that we will probably only need the
   testing ID of the expression, but having the whole thing at hand makes
   debugging easier. Probably we will change this later...
