This patch enables two new flags for the tools/test.py script;
--shard-count - giving the ability to split the tests to be run
into shard-count chunks.
--shard-run - giving the ability to specify which of the shards to actually run.
Example
tools/test.py -j15 --shard-count=2 --shard-run=1 mozilla
would split the mozilla tests into two chunks and run the tests in the first chunk
Running:
tools/test.py -j15 --shard-count=2 --shard-run=1 mozilla
tools/test.py -j15 --shard-count=2 --shard-run=2 mozilla
is equivalent (in terms of test coverage) of just running:
tools/test.py -j15 mozilla
In addition, tests are now sorted before they are returned from the
test specific ListTests methods (sputnik and mozilla tests where
already sorted before they where returned).
This change is needed to split a single test suite over two slaves on
the waterfall.

First cut at bug 992
Fixes JS portion of DefineOwnProperty when there is
an existing property and the new descriptor is generic.
Makes code follow spec steps more closely.
Fixes typo for check for unchanged enumerable in step 6.
Adds regression test.

If the instanceof stub was requested to deliver true/false objects as the result instead of 0/1 then 0/1 was actually returned if the builtin INSTANCE_OF ended up being called. This is now fixed.

methods rely on the time values passed in being within a certain range
- not significantly larger than the the ECMA 262 specified time
range. When creating a time, always make it NaN if there is no way
that it can be within range even after UTC conversion.

In the past we only accepted functions as argument for setting an
accessor. Since one should be able to set an accessor to undefined
this had to be changed to take either.
In addition, we did not lookup properties in the prototype chain,
causing us to call the setter of an existing accessor up the prototype
chain when trying to replace an existing accessor (that was not local)
with a data property.

When entering a finally block in unoptimized code, we unconditionally
save the accumulator register in the stack in case it holds a return
value or an exception. In the case of a break, continue, or falling
off the end of the try or catch block, this value is unpredictable and
not necessarily safe for GC.

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.

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.

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. :)

When falling off the end of a function inlined in a test context, we cannot
constant fold the test of undefined away. The graph builder assumes that
control flow always reaches both branches of a test.
Instead, explicitly test and branch on "undefined". Introduce a pair of
empty blocks to hold the necessary LeaveInlined instructions.
