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.)

Always invoke HeapObjectIterator::has_next() before invoking HeapObjectIterator::next().
This is necessary as ::has_next() has an important side-effect of going to the next
page when current page is exhausted.

And to find if pointers are encodable use more precise data---top of map space, not a number
of pages, as pages might stay in map space due to chunking.

non-optimizing compiler can cope with.  By default it bails out
to the old compiler on encountering a for loop (for performance)
but with this change the --always-fast-compiler flag will enable
functions with for loops to be compiled in the non-optimizing
compiler.  Also enables the non-optimizing compiler on functions
that can be lazily compiled (again only with the flag).

This is a preparation step for including number type information
in the virtual frame. We need a common place where we can update
the number type information of the result of a binary operation
since we should not modify the state of the virtual frame elements
directly.

Recent change made rax contain garbage due to write-barrier computation.

Most of the test cases fail as the different objects according to the tests 
can not have additional properties attached to them. I will file a bug report
on the es5 conform site as they should allow this. Some of the test fails
because we still miss some of the es5 features used.

As this is only needed for internal profiling (not for DevTools),
the following approach had been chosen:

 - during snapshot creation, positions of serialized objects inside
   a snapshot are logged;

 - then during V8 initialization, positions of deserealized objects
   are logged;

 - those positions are used for retrieving code objects names from
   snapshot creation log, which needs to be supplied to tick processor
   script.

Positions logging is controlled with the new flag: --log_snapshot_positions.
This flag is turned off by default, and this adds no startup penalty.

To plug this fix to Golem, the following actions are needed:

 - logs created using 'mksnapshot' need to be stored along with VM images;

 - tick processor script needs to be run with '--snapshot-log=...' cmdline
   argument.
