Add support for getOwnPropertyDescriptor on array indices (fixes issue 599).
...
This fix adds support for retriving a property descriptor on elements. The
new version supports both fast and slow case elements. In the fast case
we always default configurable, writable, enumerable to true (we don't have
PropertyDetails for fast elements).
A few new tests are added to get-own-property-descriptor.js, I will
add a lot more to object-define-property when I add support for indices in
Object.defineProperty.

Fix: make string indexing work with Infinity.
...
NumberToUint32 that I was trying to use maps -0 to +0 (as desired) but
also maps +/-Infinity to +0, which made +/-Infinity a valid string
index. I fixed it by introducing a new runtime function with the right
semantics.

Cardmarking writebarrier.
...
- New сardmarking write barrier handles large objects and normal objects in a similar fashion (no more additional space for pointer tracking is required, no conditional branches in WB code).
- Changes to enable oldspaces iteration without maps decoding:
-- layout change for FixedArrays: length is stored as a smis (initial patch by
Kevin Millikin)
-- layout change for SharedFunctionInfo: integer fields are stored as smi on
arm, ia32 and rearranged on x64.
-- layout change for String: meaning of LSB bit is fliped (1 now means hash not
computed); on x64 padding is added.
-- layout of maps is _not_ changed. Map space is currently iterated in a special
way.

String search performance improvements:
...
* Using memchr for first/only char lookup is faster than hand-coded
loop. It processes one machine word per iteration so it helps even
more on x64.
* Tweaked badness computation in simple search. We pay only for the
first char memchr scans, not for all of them.

Fix stack corruption when calling non-function.

Fix for issue 603.
Revision r3484 removed the property name from the call stack for
call ICs. When a non-function was called via a call IC and
Function.prototype.call, an extra value was left on the stack that the
caller could not know to clean up.
Fix is to change the JS builtin used for calling non-functions. It
now gets the callee as receiver, rather than iterating stack frames
and finding it on the expression stack of its JS caller.

this causes the debug check to fails since type() asserts that the

RFC: Try to be much more careful with where we skip the write barrier by:
...
1. Avoid using SKIP_WRITE_BARRIER when we don't have to (smis).
2. Check and document the remaining uses of SKIP_WRITE_BARRIER.
3. Only allow GetWriteBarrierMode when in an AssertNoAllocation scope.
The only functional change should be in DeepCopyBoilerplate where we
no longer use the write barrier mode (because of allocations). I'm
running benchmarks to see if this has a measurable impact on performance.

Fix issue 553: function frame is skipped in profile when compare stub is called.
...
The problem appeared due to a fact that stubs doesn't create a stack
frame, reusing the stack frame of the caller function. When building
stack traces, the current function is retrieved from PC, and its
callees are retrieved by traversing the stack backwards. Thus, for
stubs, the stub itself was discovered via PC, and then stub's caller's
caller was retrieved from stack.
To fix this problem, a pointer to JSFunction object is now captured
from the topmost stack frame, and is saved into stack trace log
record. Then a simple heuristics is applied whether a referred
function should be added to decoded stack, or not, to avoid reporting
the same function twice (from PC and from the pointer.)

Remove the different length string types
...
The different length string types was used to encode the string length and the hash in one field. This is now split into two fields one for length and one for hash. The hash field still encodes the array index of the string if it has one. If an array index is encoded in the hash field the string length is added to the top bits of the hash field to avoid a hash value of zero.
On 32-bit this causes an additional 4 bytes to be used for all string objects. On 64-bit this will be half on average dur to pointer alignment.

flattening the strings and not trying too hard to traverse a big

Fixed a few cases where allocators did not respect always_allocate,
...
potentially leading to bogus FatalProcessOutOfMemory situations. Also
fixed a few cases where callers relied on getting a NewSpace object
back (to avoid write barrier overhead) which they can't when
always_allocate is in effect.

Fix warnings on Win64.
...
Set warning level to /W3 and change implicit conversions from size_t
to int. Most "fixes" are simply manifesting the implicit casts or using
a special strlen replacement that returns int.

All hidden properties of an object are stored in a value of a regular property with empty name. This property may confuse user if returned among regular properties. It should not be exposed directly by ObjectMirror. Should we want an access to these properties from debugger we need to implement an explicit method for that.
...
Current patch filters the hidden_symbol from property names returned to ObjectMirror.

Remove sliced string string type
...
As a first step to reduce the complexity of the string hierachy the sliced string type is removed. Whenever a sub-string is created it is allocated as a fresh flat string.

Don't use string slices when processing RexExp replace.
...
String slices from RegExp replace results is now encoded in either one or two smis. Substrings are not used any more.
If the existing one smi encoding cannot hold the start/length information two smis are used the first having the negative length and the second having the start.
This is in preparation for removing string slices.
