17da434b29 Remove instruction summaries. 
Instead of constructing a temporary container for all LOperands of each
instruction, the register works directly on the LIR instructions that
 provide an abstract interface for input/output/temp operands.

This saves allocation of zone memory and speeds up LIR construction,
but makes iterating over all uses in the register allocator slightly
more expensive because environment uses are stored in a linked list of
environments. We can fix this by using a flat representation of LOperands.

f1149734fc Partial fix for V8 issue 1079. 
Record a safepoint with a deoptimization id for throw in optimized code.  We
don't seem to much care what the AST ID is because we will not be using it
for lazy deoptimization (throw doesn't return to the point of throw).  For
hygiene we use the actual ID of the throw expression.  Throw is no longer a
control-flow instruction, but it's followed by an unconditional abnormal
exit.  This is required to insert a simulate between the throw and the exit.

Make our optimized treatment of Function.prototype.apply act like a call and
have side effects.  This ensures that it will get a lazy deoptimization
environment.  Use that deoptimization ID in the safepoint for the call.

Deleting a property was also missing a deoptimization ID, though there was a
deoptimization environment assigned to the instruction.  Record the
environment and use the deoptimization ID at the safepoint.

dc61921bbf Fix reintroduction of global variables that have been deleted. 
Deletion of global properties puts 'the hole' in the global property
cell and updates the property details in the property dictionary with
the information that the property has been deleted. When setting
global properties that have been deleted in generated code we just
store the new value in the global property cell. This does not update
the property details in the property dictionary. Therefore, it looks
like the property is not there eventhough it was just reintroduced.

Perform 'the hole' checks in generated code for global property stores
and bail out of ICs and optimized code if storing to a property cell
that contains 'the hole'.

76483f871b Support StringLength in hydrogen (similar to ArrayLength). 
To avoid deopts a few extra changes were needed:

o Enable megamorphic state for special property loads on
  primitives. We used to flip between monomorphic stubs.
o Extract pure string (no string wrapper support) version of the
  string length stub.

99a5b9f713 ARM: Initial type recording binary operation stub 
This implements the type recording binary operation stub for ARM. This first iteration only supports ADD. Handling of 32-bit integers is currently not implemented but just transitions. The generic case for now delegates to the generic binary operation stub.
