36477ee160 Use registers to pass arguments to GenericBinaryOpStub. 
Currently arguments are never passed on registers (due to the way ArgsInRegistersSupported is written) and
if they were, the stub would break in several places because registers are not preserved properly in the
course of execution. This CL makes use of registers more often (than never) and makes sure that registers are
handler properly.
A peformance gain is small (0.2-0.3%) but stable.
This CL was extracted from the one sent out earlier (http://codereview.chromium.org/551093).

4d3a5968a5 Inline smi code in count operations in the full code generator. 
We now test for a smi before calling ToNumber and inline
the smi increment/decrement for ++ and --. There only a small
increase in code size but loops in top-level code are
becoming much faster as a result.

40fd97c87d A follow-up to fix 553: really report function object moves. 
As an afterthought, I realized that I put function objects moves
reporting into a method that deals with only code object moves.  I've
looked up that function objects are allocated in old pointer space and
new space, so I moved logging to the corresponding VM methods.

999e3fca90 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.)

d587851d7f Fix map compact implementation. 
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.

c80cba3bcc Add the for statement back into the set of things the 
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).
