Implemented missing pieces of the debugger for ARM.
...
The main piece of this change was to add support for break on return for ARM. On ARM the normal js function return consist of the following code sequence.
mov sp, fp
ldmia sp!, {fp, lr}
add sp, sp, #4
bx lr
to a call to the debug break return entry code using the following code sequence
mov lr, pc
ldr pc, [pc, #-4]
<debug break return entry code entry point address>
bktp 0
The values of Assembler::kPatchReturnSequenceLength and Assembler::kPatchReturnSequenceLength are somewhat misleading, but they fit the current use in the debugger. Also Assembler::kPatchReturnSequenceLength is used in the IC code as well (for something which is not related to return sequences at all). I will change that in a separate changelist.
For the debugger to work also added recording of the return sequence in the relocation info and handling of source position recording when a function ends with a return statement.
Used the constant kInstrSize instead of sizeof(Instr).
Passes all debugger tests on both simulator and hardware (only release mode tested on hardware).

Add support for (some) assignment expressions to the CFG builder and
...
fast-mode compiler.
1. We avoid generating a useless temporary for assignments with
nontrivial right-hand sides. Instead of translating id = expr into:
...
tmp = <last expr instruction>
id = tmp
we generate directly
...
id = <last expr instruction>
by passing a data destination ('hint') down the AST. The semantics is
to use the destination as a result location if a temp is needed. It
may be ignored. NULL indicates I don't care and you should generate a
temp.
2. We correctly handle assignments as subexpressions. When building
the CFG for an expression we accumulate the assigned variables and we
emit a move to a fresh temporary if a value in a variable is in
jeopardy of being overwritten.

Changed the global object representation.The global object is now always in dictionary (slow) mode with each of its properties stored in a cell object. A cell object has one field containing the actual value for the property. Inline caches for access to global properties which uses direct to the cell are now created for load, store and call to properties of the global object. When properties of the global object are deleted the cell for that property is kept with an indcation of that the property is deleted.Added counters to track the use of the global property inline caches.Added additional information on IC's in the disassembler.

* Modify simulator and ARM code generator to avoid swi
...
instructions. The intention is that the snapshots generated
by the simulator should be usable on the hardware. Instead of
swi instructions we generate a branch to a swi instruction that
is not part of the snapshot. The call/jump is patched up in
the same way as other external references when the snapshot
is deserialized. This only works for EABI targets: on old ABI
targets we still emit some instructions not supported by the
simulator (fp coprocessor instructions).

Simplify the processing of deferred code in the code generator. Our
...
deferred code snippets are highly stylized. They always make a call
to a stub or the runtime and then return. This change takes advantage
of that.
Creating a deferred code object now captures a snapshot of the
registers in the virtual frame. The registers are automatically saved
on entry to the deferred code and restored on exit.
The clients of deferred code must ensure that there is no change to
the registers in the virtual frame (eg, by allocating which can cause
spilling) or to the stack pointer. That is currently the case.
As a separate change, I will add either code to verify this constraint
or else code to forbid any frame effect.
The deferred code itself does not use the virtual frame or register
allocator (or even the code generator). It is raw macro assembler
code.

This patch much improves our tracking of whether function is
...
called from within a loop or not. In the past we lost the
information if a call site went megamorphic before a lazily
compiled callee was called for the first time. Now we track
that correctly (this is an issue that affects richards).
We still don't manage to track the in-loop state through a
constructor call, since constructor calls use LoadICs instead
of CallICs. This issue affects delta-blue. So in this patch
we assume that lazy compilations that don't happen through a
CallIC happen from inside a loop. I have an idea to fix this
but this patch is big enough already.
With our improved tracking of in-loop state I have switched
off the inlining of in-object loads for code that is not in
a loop. This benefits compile speed. One issue is that
eagerly compiled code now doesn't get the in-object loads
inlined. We need to eagerly compile less code to fix this.

Materializing a frame element on the stack by pushing it can cause the
...
stack pointer to change by more than one in a corner case. If we push
a constant smi larger than 16 bits, we push it via a temporary
register. Allocating the temporary can cause a register to be spilled
from the frame somewhere above the stack pointer.
As a fix, do not use pushes to materialize ranges of elements of size
larger than one.
