Valgrind cleanliness, part 1: Delete current isolate on exit.
...
Currently we leak 140kB from 80 allocation sites when we evaluate a simple
"print(1+2)" in d8 and exit. This might not be a real problem in Chrome because
most of the time the whole process containing v8 vanishes, but it can hide real
leaks in a sea of false positives. Therefore, this CL and a few subsequent ones
clean this up a bit.
This simple CL alone fixes 45 leaks, leaving only 35 with a net loss of 2192
bytes (on ia32).

Original commit message:
If all property lookups for a polymorphic load actually result in the
same field index under all maps, we can actually emit a monomorphic load
that is guarded by a map check that verifies that the actual map is in
the set of handled maps. This also allows GVN to get rid of redundant
such map checks.

Make setting of accessors even more atomic.
...
Now the whole getter/setter/attributes triple gets created/set together,
avoiding any hacks regarding previous values/attributes, making things a lot
simpler.
While doing this, an interesting problem surfaced, which has been there for a
long time: After adding/changing acessors in slow mode, we could potentially
fail going back to fast mode because of a failed memory allocation, signaling
the need for a GC. But we have already changed the object in slow mode, so we
are not idempotent and the retry would trigger a newly inserted assertion
(namely, that the code obeys access restrictions). This has been solved by
splitting the transformation to fast mode from the actual setting of the
accessors.

MIPS: Branch delay slot and other optimizations.
...
List of changes:
-added a minor optimization to the Simulator that quickly skips nops in the delay slot
-slightly re-worked CEntryStub to save a few instructions
CEntryStub now expects the following values:
-s0: number of arguments including receiver
-s1: size of arguments excluding receiver
-s2: pointer to builtin function
Two new MacroAssembler functions were added to make usage more convenient:
-PrepareCEntryArgs(int num_args) to set up s0 and s1
-PrepareCEntryFunction(const ExternalReference&) to set up s2
-removed branch delay slot nops from the most frequently used code areas
-reorganized some code to execute fewer instructions
-utilized the delay slot of most Ret instructions
This does not cover all Rets, only the most obvious cases.
Also added a special version of DropAndRet that utilizes the delay slot.
-added some comments to code areas where explanation of the register/delay slot usage may be needed
-added an optimization to Jump so it doesn't always pre-load the target register

Insert explicit deoptimization for named loads that have "uninitialized" type feedback.
...

When transitioning LoadIC to megamorphic case place monomorphic stubs into stub cache.
...
