DefineOwnProperty (changed to allow for redefinition of existing property)

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.

in particular).
* Called function is passed on the stack instead of
using a static variable.
* Builtins that don't need the called function don't
get it.
* Made is_construct statically known to HandleApiCall
by setting custom construct stub for API functions.

for partial snapshots. After reserving space we can be sure that allocations
will happen linearly (no GCs and no free-list allocation). This change also
contains the start of the partial snapshot support, which, however is not yet
completed or tested.

Added newly added instructions to test-disasem-ia32.cc and implemented the missi
ng ones in the disasembler.
Added some asserts to 8-bit instructions which only work with eax, ebx, ecx and
edx (al, bl, cl and dl).
Removed the loope instruction.
