179aef2b8f VM initialization refactoring. 
This patch introduces global once per-process initialization and moves
the OS and CPU setup there. This makes CPU features isolate-independent.

a968ed0470 Implement HeapIterator that skips over unreachable objects. 
I'm using it when creating heap snapshots. I decided that it will
be more convenient to have it as a separate piece of code, instead
of embedding into the snapshot generator.

2a8eb35548 Provide more accurate results about used heap size via GetHeapStatistics. 
I observed that used heap size provided by Heap::SizeOfObjects() is
usually about ~10% bigger than the number calculated by summing up
heap objects sizes.

This aligns DevTools Timeline stats with Heap profiler stats.

9673ee5d59 Get rid of requested size in RetryAfterGC. 
This was only used by Heap::CollectGarbage to check if after GC
available space is bigger than was requested, but nobody checked
the value returned by Heap::CollectGarbage, so requested size
was efficiently unused.

However, it may trigger spurious out of memory exceptions if requested
size is big enough.

793d0a92b9 Add a check that weak object handle is not in NEAR_DEATH state after weak callback invocation. 
If object enters NEAR_DEATH state, it must be explicitly cleared and/or disposed, otherwise
it would retain JS object forever.  Note as well that parameter is reset to NULL on first
invocation so weak handle callback would be in hard situation.

- 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.

Otherwise page header check is not quite robust: if there is a smi

be returned.

That shouldn't be the problem for paged spaces as objects in those
pages do not span page boundaries and thus cannot mess with ::is_normal_page field.

eb4d261e24 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.
