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.
...
We already do this for binary-ops, unary-ops and comparisons. Typefeedback for named loads can now also
be in "uninitialized" state which means that the corresponding load IC was never executed.

Fix declarations escaping global strict eval.
...
According to ES5 10.4.2(3), eval calls of strict code always require
their own lexical and variable environment. For now we just add a new
scope when we parse the strict mode directive. The clean solution would
be to always have this sope present (even for global eval calls) and
adapt variable binding to cope with that.

Ensure that generated code for object literals will call Runtime_DefineOrRedefineAccessorProperty only once per accessor property.
...
To do this, we collect all accessor properties in a first pass and emit code for
defining those properties afterwards in a second pass.
As a finger exercise, the table used for collecting accessors has a (subset of
an) STL-like iterator interface, including STL-like names and operators.
Although C++ is quite verbose here (as usual, but partly this is caused by our
current slightly clumsy classes/templates), things work out quite nicely and it
cleans up some confusion, e.g. a table entry is not an iterator etc.
Everything compiles into very efficient code, e.g. the loop condition 'it !=
accessor_table.end()' compiles into a single 'testl' instruction on ia32.
+1 for using standard APIs!

Landing for pliard@chromium.org: Remove static initializers in v8.
...
This change includes two CLs by pliard@chromium.org:
1. http://codereview.chromium.org/9447052/ (Add CallOnce() and simple LazyInstance implementation):
Note that this implementation of LazyInstance does not handle global destructors (i.e. the lazy instances are never deleted).
This CL was initially reviewed on codereview.appspot.com:
http://codereview.appspot.com/5687064/
2. http://codereview.chromium.org/9455088/ (Remove static initializers in v8):
This CL depends on CL 9447052 (adding CallOnce and LazyInstance).
It is based on a patch sent by Digit.
With this patch applied, we have only one static initializer left (in atomicops_internals_x86_gcc.cc). This static initializer populates a structure used by x86 atomic operations. It seems that we can hardly remove it. If possible, it will be removed in a next CL.
This CL also modifies the presubmit script to check the number of static initializers.

Add clobber list to arm inline asm.
...
While enabling "-fstack-protector", compiler generates code in
function prologue and epilogue to do stack check. However, without
knowing that 'r1', 'r2' and 'r3' is used/destroyed in inline asm,
compiler assumes that 'r1', 'r2', or 'r3' can be used exclusively,
which leads to a core dump.
Fix to this is quite straightforward, just add clobber list to the
inlineasm.

2. The backing store for smi-only elements can only be reused for

a fresh one because the old one is in pointer-space and the new one
has to be in data-space.

Basic interface inference for modules.
...
All module expressions, and all variables that might refer to modules,
are assigned interfaces (module types) that are resolved using
unification. This is necessary to deal with the highly recursive
nature of ES6 modules, which does not allow any kind of bottom-up
strategy for resolving module names and paths.
Error messages are rudimental right now. Probably need to track
more information to make them nicer.

Make the runtime entry for setting/changing accessors "atomic".
...
Previously, there were 1 or 2 calls to the runtime when accessors were changed
or set. This doesn't really work well with property attributes, leading to some
hacks and complicates things even further when trying to share maps in presence
of accessors. Therefore, the runtime entry now takes the full triple (getter,
setter, attributes), where the getter and/or the setter can be null in case they
shouldn't be changed.
For now, we do basically the same on the native side as we did before on the
JavaScript side, but this will change in future CLs, the current CL is already
large enough.
Note that object literals with a getter and a setter for the same property still
do 2 calls, but this is a little bit more tricky to fix and will be handled in a
separate CL.
