76833936b7 Make Array::kHeaderSize protected, and only use kHeaderSize of its subclasses.
Many X64 bugs have been due to the difference between (unaligned) Array::kHeaderSize and (aligned) FixedArray::kHeaderSize.

The flag is only turned on when --trace_gc is one. It prints out used and available bytes in each space. To enable it, ENABLE_LOGGING_AND_PROFILING must be defined.

This is a mini version of --heap_stats, but don't need DEBUG macro to be turned on.

d0c35af612 Create a new paged heap space for global property cells. The new
space is similar to map space in that it has fixed-size objects.  A
common superclass for a space with fixed size objects is used for the
map space and cell space.

Allocate all cells in cell space.  Handle it during all GCs.  Modify
the free-list node representation (so that the size is not at a fixed
offset in all cells) to allow two-pointer free-list nodes.  Clean up
some stuff in the MC collector.

cba9c183a0 In Chrome several tabs may share the same v8 instance. Each of those tabs can be inspected with its own devtools window. When such devtools window closes we need to clear all breakpoints that belong to it. Notion of breakpoint group enables us to do that.
Storing the breakpoints on the client(in a different process) would be inreliable since 1) it may crash and 2) some 'setbreakpoint' requests may be not processed yet by the time devtools window closes.

25405ddd9c Handle JavaScript accessors on the global object.
With the new representation of the global object adding JavaScript accessors for a property after global inline caches was created for that property did not work property as the inline caches did not take the JavaScript accessor information (fixed array with two elements) that could be present in a global object property cell into account.

This is now fixed by changing the map for a global object when a JavaScript accessor is defined on it.

8318f5e5f1 Reimplement profiler sampler on Mac OS X to get it working under Chromium.
Previous implementation of sampler for OS X was copied from the Linux one. But BSD (OS X) and Linux has a very important difference in signal handling. LinuxThreads doesn't support the notion of process-directed signals. So, the SIGPROF signal was directed to the thread that installed the handler---the V8 thread. But on BSD, signal handling is implemented according to POSIX spec, where process-directed signal is to be handled by an arbitrary selected thread. By a coincidence, in V8's sample shell and in Chromium's test shell, V8's thread was picked almost every time, so sampling seemed working. But not in case of Chromium.

So, I've changed the implementation of profiler sampler to use the same scheme as on Windows---a dedicated thread with high priority is used to periodically pause and sample V8's thread.

Propegate the in loop flag for the global call inline cache.

Changed the propagation of the code flags in the call stub compiler to compute these the same way for all types of call stubs and assert that the flags for the generated code is the same as those used for the cache lookup.

118a2ccc8e When Error.collectStackTraces is set to true all new instances of
Error, ReferenceError, etc. are given a stack property that gives a
stack trace.  Here's an example stack trace:

ReferenceError: FAIL is not defined
    at Constraint.execute (deltablue.js:527)
    at Constraint.recalculate (deltablue.js:426)
    at Planner.addPropagate (deltablue.js:703)

    at Planner.incrementalAdd (deltablue.js:593)
    at Constraint.addConstraint (deltablue.js:164)
    at Constraint.BinaryConstraint (deltablue.js:348)
    at Constraint.EqualityConstraint (deltablue.js:517)
    at chainTest (deltablue.js:809)
    at deltaBlue (deltablue.js:881)
    at deltablue.js:888

If Error.prepareStackTrace holds a function this function is used to
format the stack trace, for instance allowing code generators to
customize the way stack traces are reported to make them easier to
process.

Next step: performance measurements to see if it is feasible to turn
this on by default.

a54a4ada5c Changed the global object representation.The global object is now always in dictionary (slow) mode with each of its properties stored in a cell object. A cell object has one field containing the actual value for the property. Inline caches for access to global properties which uses direct to the cell are now created for load, store and call to properties of the global object. When properties of the global object are deleted the cell for that property is kept with an indcation of that the property is deleted.Added counters to track the use of the global property inline caches.Added additional information on IC's in the disassembler.
