54d6072332 Change the handling of stack check on backward branches 
The hydrogen stack check instruction is now added to each loop and the stack check handling on the back edge has been removed.

This change causes regression on small tight loops as the stack check is now at the top of the loop instead of at the bottom, and that requires one additional unconditional jump per loop iteration. However the reason for this change is to avoid worse regressions for upcoming changes to correctly support debugger break in optimized code.

5b7b0ce861 Limit the size of the space reserved for code on systems that 
are short of virtual memory.  This should make V8 work in 64 bit
on OpenBSD in its default configuration.  It is a simplified
version of the reverted 8133 which also lowered the non-code
heap size, causing test failures in Chromium on MacOS.

0bb0d672b6 Make ToBooleanStub more consistent across platforms. 
The declaration of the ToBoolean class moved to the platform-independent part
and its implementations are now structurally very similar. This is just an
intermediate cleanup step to add type recording at the call site.

Note that the MIPS implementation has not really been touched, so it should
continue to work, too.

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.

This is a regression relative to the original behavior, when "native" was a keyword,
since keywords cannot contain esacpes.

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...

508b22c436 "Deiceolate" Thread classes. 
Thread class was receiving an isolate parameter by default.
This approact violates the assumption that only VM threads
can have an associated isolate, and can lead to troubles,
because accessing the same isolate from different threads
leads to race conditions.

This was found by investigating mysterious failures of the
CPU profiler layout test on Linux Chromium. As almost all
threads were associated with some isolate, the sampler was
trying to sample them.

As a side effect, we have also fixed the DebuggerAgent test.

Thanks to Vitaly for help in fixing isolates handling!

e9a1ffde92 Stop using with explicitly to implement try/catch. 
The AST for TryCatch gives us enough structure that we do not need to expand
it to explicitly include a with.  Try/catch is still handled the same as
before at runtime.

2dc734c108 Cleanup unused lithium instructions. 
Instructions that have side effects can never have EmitAtUses() true.
These instructions (CmpTAndBranch, InstanceOfAndBranch) are therefore
never generated and can therefor be safely removed.

59485c1060 Add snapshot compression support into d8. 
I'm not bothering with compressing d8.js, since it makes no sense,
but it is also possible.

3b2470d296 Fix presubmit errors catched by a more recent version of cpplint.py. 
Mainly, there were errors concerning blank lines before and after class access
control sections [whitespace/blank_line].

BEFORE an access control section (e.g. public:, private:) there should be a
blank line (except for the section right after the class declaration).

AFTER an access control section there should be no blank line.
