Replaced IsValid by IsPropertyOrTransition and used IsProperty in most
of the places where IsValid was used before. Most of the time when
inspecting a lookup result we really want to know if there is a real
property present. Only for stores are we interested in transitions.

Moved all the logic to a function on SharedFunctionInfo (including the flag check) to make things more readable.
Changed the check for setter to do a lookup for a named setter for each of the properties assigned in the constructor.
Added tests using accessors and interseptors set through the API.
Added fast case objects to the mjsunit test.

This change allows to associate integer tags with blocks of profiler
log events, and repeat calls to 'ResumeProfiler' / 'PauseProfiler' in
order to establsh nested (not necessary properly nested) blocks. By
supporting this, we will be able to match WebInspector's CPU profiler
abilities in DevTools.
I also refactored some testing code.

With the current API the embedder has to extrenalize a string each
time a string is encountered to avoid the cost of repeated character
copying/conversion. The issue here is that the externalization cost
itself is non-negligible (both in time and space) and should not be
paid for a rarely used string. This change is an attempt to predict a
string's usage frequency based on its freshness. A string is
considered fresh if it was recently allocated in the new space.

DefineOwnProperty (changed to allow for redefinition of existing property)
SameValue
Extra info on propertydescriptor
GetProperty
HasProperty
Currently the DefineOrRedefineAccessorProperty deletes the existing
property on the object if it is a dataproperty (FIELD or NORMAL) and
adds a new one. This can potentially be optimized.

objects in the startup heap from a partial snapshot. This happens
through the partial snapshot cache. A startup snapshot and a
partial snapshot are created together so that the startup snapshot
contains the partial snapshot cache entries needed.

As the start index is already passed it is easy to calculate the "at start" boolean in generated code. Also as direct entry has been implemented this needs to be done in generated code anyway, and therefore might as well be moved to the generated code for RegExp. The "at start" value is now calcualted as a local variable on the native RegExp frame based on the value of the start index argument.
The x64 version have been tested on both Linux and 64-bit Windows Vista.
For ARM I have tested cctest/test-regexp on ARM hardware, but the rest of the tests have only been run on the ARM simulator.

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.

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.
