SVN revision 5993 ported changes to the unoptimizing compiler from
ia32 to ARM and x64. A call to AstContext::Plug was moved out of
FullCodeGenerator::EmitVariableAssignment and into the callers. One
call site was missed in both ports.

This is based on the structore used in chromium with a script wrapping the call to gyp itself and the default processing of common.gypi.
It is possible to build all our targets on Intel Linux for all architectures (ia32, x64 and ARM simulator). When this is committed I wil take a look at Windows.
See the README.txt file in the changelist for the current way of using it.

This fixes V8 issue 989.
Before, assignments used the AST ID of the assignment expression to
mark the side effect of the store, which became a target for
deoptimization bailout for code after the assignment. In effect
contexts this environment included the value of the assignment, which
was unexpected by the unoptimized code.
Now we introduce a new assignment ID for AST node types that include
an assignment (Assignment, CountOperation, and ForInStatement) and use
it for the side effect of the store.

Adding experimental JavaScript internationalization API to V8 as an
extension. This CL implements Locale object only.
Each embeder has to decide whether to include this extension or not by
editing their build rules.
See ecmascript strawman document for details on i18n
API. http://wiki.ecmascript.org/doku.php?id=strawman:i18n_api
TEST=WebKit CL (in progress) will have layout tests for extension.

idle notifications after the one that causes the mark-compact
collection unless four or more garbage collections (scavenges) have
occurred.
The embedder should stop sending idle notifications once V8 returns
true from the IdleNotification call. This change is being defensive so
it will not hurt as badly if embedders continue to send idle
notifications.

As taking a snapshot of a large heap takes noticeable time, it's
good to be able to monitor and control it.
The change itself is small, big code deletes and additions are in
fact moves. The only significant change is simplification of
approximated retained sizes calculation algorithm.

In the case of inlined smi code in non-optimzied code we could not
distinguish between the smi-only case and the case that the operation was
never executed.
With this change the first execution of a binary operation always jumps
to the stub which in turn patches the smi-check into the correct
conditional branch, so that we benefit from inlined smi code after the
first invocation.
A nop instruction after the call to the BinaryOpIC indicates that no
smi code was inlined. A "test eax" instruction says that there was smi
code inlined and encodes the delta to the patch site and the condition
code of the branch at the patch site to restore the original jump.

SplitBetween (formely known as Split with 3 arguments) should select split position from [start, end] instead of [start, end[. This should also improve allocation quality (remove certain redundant move patterns).
Also some minor renaming and refactoring to make register allocator code more readable.

that ip can be used as a scratch register. This is not true because
ip is already used for something else in AllocateInNewSpace in the
macro assembler.
Explicitly allocate a temp register for use in the heap number
allocation instead.

x64 where crankshaft is not the default. Add ability to add custom
expectations for running in this special crankshaft mode.
The expectations are not updated in this change. There are a couple of
bugs that I would like to fix before doing that. Otherwise the lists
will be very long. :)
