Do not add values to HGraph in Lithium.
...
Lithium uses indexes after the maximium value ID in the HGraph as indexes
of virtual registers and assumes that the maximum value ID does not change.
The IsStandardConstant and GetConstantXX functions could add constants to
HGraph, which aliased virtual registers with real values. This could confuse
the register allocator to think that a value in a virtual register is tagged
and to incorrectly set it in the pointer map.

Allow redirecting disassembly and deoptimization traces into a file.
...
This is controlled by two flags:
--redirect_code_traces
--redirect_code_traces_to=<filename>
When redirection is enabled but --redirect_code_traces_to is not specified traces are written to a file code-<pid>-<isolate>.asm. This mangling scheme matches hydrogen.cfg and allows easy discovery of compilation artifacts in a multi-V8 environment (e.g. when compilation is traced from inside Chromium).
D8 defines --redirect_code_traces_to=code.asm similar to hydrogen.cfg redirection.

MIPS: Improve implementation of HSeqStringSetChar.
...
Port r17521 (c51c75e)
Original commit message:
This improves the generated code for HSeqStringSetChar across
all platforms, taking advantage of constant operands whenever
possible. It also drops the unused DefineSameAsFirst constraint
for the register allocator on x64 and ia32, where it caused
unnecessary spills when the string operand was live across the
HSeqStringSetChar instruction.
A new GVN flag StringChars is introduced to express dependencies
between HSeqStringSetChar, HStringCharCodeAt and the upcoming
HSeqStringGetChar (the GVNFlags type is now 64bit in size).
Also improves the test case.

MIPS: Correct handling of arrays with callbacks in the prototype chain.
...
Port r17525 (55b95f3)
Original commit message:
Our generic KeyedStoreIC doesn't handle the case when a callback is
set on array elements in the prototype chain of the object, nor do
we recognize that we need to avoid the monomorphic case if these
callbacks exist.
This CL addresses the issue by looking for dictionary elements in
the prototype chain on IC misses and crankshaft element store
instructions. When found, the generic IC is used. The generic IC is
changed to go to the runtime in this case too.
In general, keyed loads are immune from this problem because they
won't return the hole: discovery of the hole goes to the runtime where
the callback will be found in the prototype chain. Double array loads
in crankshaft can return the hole but only if the prototype chain is
unaltered (we will catch such alterations).
Includes the following patch as well (already reviewed by bmeurer):
Performance regression found in test regress-2185-2.js. The problem was
that the bailout method for TransitionAndStoreStub was not performing
the appropriate transition.

Handlify ForceSetObjectProperty
...
Note that I've left the layering as is to make the diffs clear. Is it worth moving ForceSetObjectProperty to objects.cc? This code is clearly implementing part of the DefineOrRedefine steps from the spec, but it's still odd that it lives in Runtime. Note that handles.cc exposes a ForceSetProperty which just performs a CALL_HEAP_FUNCTION on the Runtime::ForceSetObjectProperty -- which is exposed to the api as v8::Object::ForceSet
