Before, an attempt to delete a parameter in a function that used the

the parameter and the corresponding arguments object property.
Now, an attempt to delete such a parameter does not delete and
evaluates to false.
Parameters can be deleted, as before, from functions that use the
arguments object, by deleting the corresponding arguments object
property (this is a spec violation).

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.

Streamline the code for patching optimized code for lazy deopt.
...
Rewrite the lazy deopt patching code on IA32 to use addresses throughout,
rather than offsets and a base address.
Also, rename a couple of ambiguous Code fields from _start to _offset.

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.
