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.

32cd13ebf1 Remove the redundant load on every context lookup. 
There was an unnecessary load on every statically-resolved context lookup.
Remove it.

This revealed a hidden bug in const initializers inside 'with'.  They claim
to be statically resolved (having slot type CONTEXT) but they occur in a
spot where the runtime context chain and the static scope chain do not
agree.  This is fixed by special casing const initializers in the backend.

It made value of allowed_access_type[v8::ACCESS_KEYS] be a wild value.  On most of
platforms it was 0 and tests passed.  But on ARM (and on ia32 if you alter test a bit)
it could become true and hence allow enumeration of properties.

2d9c65901b Heap profiler: fix removed DOM wrappers reporting. 
Aggregated snapshots: don't report unreachable objects.
Full snapshots: restore forcing GC prior to taking a snapshot.

I played with the repro page provided for the bug and found that GC
must be performed prior to taking a snapshot even if we only report
reachable objects. GC allows weak handles to finalize.  Now heap
profiler produces aligned results for the repro page in both modes.

Current approach returns undefined descriptor if caller is not granted v8::HAS_ACCESS.
If the caller has v8::HAS_ACCESS, for no JS accessors regular v8::GET_ACCESS check is
performed and value property of the descriptor is set to undefined if caller doesn't
have proper access.  For JS accessors both v8::GET_ACCESS and v8::SET_ACCESS are checked
and affect if getter and setter would be stored in the descriptor.

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.

cb0a7bc748 This fixes the issue with the deoptimizer trashing the reloc info before patching the code. 
If we, immediately after the deoptimization, but before actually
running the patched code, get a compacting GC, the addresses from the
calls might no longer be valid.

I have validated that this works by patching the existing code to
always do a compacting gc after we finish deoptimizing. I will create
a real regression test for this, but this includes additional code for
allowing us to force a deopt/opt from javascript test code. I will
land this in a seperate change.

2c93e885f3 Switch from template functions overloading to partial template specialization. 
This should fix compilation on old GCC.
