64c897b5cb Extend gdb-jit support (OSX/locals+parameters/prettyprint) 
Generate Mach-O in-memory objects for OSX. Dump locals and parameters
for non-optimized frames.

Unfortunately, it seems like more-recent-GDB on OSX there is a little
temperamental (eg, the version from macports will be missing symbols
from gdb-integration_g when the version included in xcode will not--
and this is with --gdbjit off).

Includes some Python scripts to make dealing with V8 values in gdb more
pleasant.

Ported 8452 (8a2a360)

Original commit message:
Before: every context cached the nearest enclosing function context. This
assumed that for nested contexts (i.e., with and catch contexts) the
enclosing function had a materialized link in the context chain.
Now: when necessary, we loop up the context chain to find such a context.
This enables catch contexts without forcing the enclosing function to
allocate its own context.

90c9f1b989 Suspend runtime profiler as soon as we exit JS. 
Lots of web pages have really frequently firing timers that keep the
profiler thread spinning if we require a period of JS inactivity
before suspending the profiler. While it's possible to throttle it by
increasing the sleep delay and adjusting the duration of the required
inactive period, it seemed much simpler to just stop it immediately on
exiting JS.

Stopping the profiler this way effectively turned off two optimization
heuristics: 1) eager optimization (it's reset on waking up the
profiler and now the profiler wakes up much more frequently) and 2)
optimization throttling based on JS to non-JS state ratio (the ratio
is now 100%). I removed these two heuristics and found no performance
regressions so far.

7d2be7c0e0 Support debugger inspection of locals in optimized frames 
Optimized frames are now handled by the debugger. When discovering optimized frames during stack inspection in the debugger they are "deoptimized" using the normal deoptimization code and the deoptimizer output information is used to provide frame information to the debugger.

Before this change the debugger reported each optimized frame as one frame no matter the number of inlined functuions that might have been called inside of it. Also all locals where reported as undefined. Locals can still be reposted as undefined when their value is not "known" by the optimized frame.

As the structures used to calculate the output frames when deoptimizing are not GC safe the information for the debugger is copied to another structure (DeoptimizedFrameInfo) which is registered with the global deoptimizer data and processed during GC.

The receiver needs to be checked in the same way as all other KeyedLoadICs to take non-JSObject and objects that require access checks or has interceptors into account.

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.

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).

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!

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.

5872e8ee2f Refactor storage of global handles. 
We used to have a linked list of nodes that were internally
block-allocated.

I kept the node blocks and put them on two lists: 1) the list of all
allocated blocks, 2) the list of blocks with used nodes. (1) is used
to reclaim blocks and (2) is used for traversal during GC. To make
traversal on scavenges faster the nodes holding new space objects are
grouped in an auxiliary array.

This changes the minimal memory usage from 5 words per global handle
to 4. Additional word is used for new space handles.

I'm removing the test GlobalLoadICGC test that was introduced for testing
inlined global cell loads (in the classic backend) and has an invalid assumption
about the number of global objects referenced from a v8 context. We don't have
this feature with Crankshaft anymore.

0c1702b199 Don't use SmartSlice just because the receiver is an array. 
Only do so if the estimated number of elements is low compared to the
end position for the slice. This is similar to other heuristics used
for array operations that use the %GetElementKeys runtime function.

6a81642f31 Fix a bug in Lithium environment iteration. 
The Advance() function of the class responsible for iterating
environment uses didn't always advance as far as it could (relying on
the HasNext predicate to finish advancing).  This is brittle.

The HasNext predicate also didn't advance as far as it could when it
was at the end of an environment level.  This is a bug.

0163b443d2 MIPS: port Implement set trap for proxies, and revamp class hierarchy in preparation 
Ported commits: r8126 (6461bae)

Original commit message:
- Introduce a class JSReceiver, that is a common superclass of JSObject and
JSProxy. Use JSReceiver where appropriate (probably lots of places that we
still have to migrate, but we will find those later with proxy test suite).
- Move appropriate methods to JSReceiver class (SetProperty,
GetPropertyAttribute, Get/SetPrototype, Lookup, and so on).
- Introduce new JSFunctionProxy subclass of JSProxy. Currently only a stub.
- Overhaul enum InstanceType:
* Introduce FIRST/LAST_SPEC_OBJECT_TYPE that ranges over all types that
represent JS objects, and use that consistently to check language types.
* Rename FIRST/LAST_JS_OBJECT_TYPE and FIRST/LAST_FUNCTION_CLASS_TYPE
to FIRST/LAST_[NON]CALLABLE_SPEC_OBJECT_TYPE for clarity.
* Eliminate the overlap over JS_REGEXP_TYPE.
* Also replace FIRST_JS_OBJECT with FIRST_JS_RECEIVER, but only use it where
we exclusively talk about the internal representation type.
* Insert JS_PROXY and JS_FUNCTION_PROXY in the appropriate places.
- Fix all checks concerning classification, especially for functions, to
use the CALLABLE_SPEC_OBJECT range (that includes funciton proxies).
- Handle proxies in SetProperty (that was the easiest part :) ).
- A few simple test cases.
