a7c743d3ac Reuse the gap move resolver. 
Rather than allocating a fresh gap move resolver for every parallel
move, use a single one per Lithium code generator.  This avoids always
reallocating the temporary zone-allocated lists used by the gap move
resolver.

a0bc9eb040 Add more bailouts for Array.slice over arguments. 
Unfortunately, arguments is pretty much the normal JS object.  For now
I am adding more sanity checks (in hope that typically arguments
list is rather short.)  However it probably requires more systematic
treatment, for example, we could optimistically copy elements until
we meet first hole and in this case resort to JS builtin.

b4ea8c7f5e Enable sharding of individual testsuites in tools/test.py 
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.

cd4ae721e2 ARM: Implement delete operation in lithium codegen. 
I'm using the post call generator for the macro assembler
InvokeBuiltin call to be consistent with the ia32 version. It only
generates one call, but using the post call generator it should be
easier to catch if we change that at some point.

f89ce8159a Split LInstruction into multiple variant to make our LIR more compact. 
This change introduces LTemplateInstruction which is a specialized version
of LInstruction and takes one template parameter to indicate whether the
instruction produces a result operand.

All instruction that do not have a result inherit from LTemplateInstruction<0>.
Instructions that have a result operand from LTemplateInstruction<1>

All the Define* function only operate on instructions with a result.

For this to work I also refactored the places where we do 

  LInstruction* result = new Lxyy

into

  Lxyz* result = new Lxyz

426f13e084 Fix GC issue in instanceof stub 
The the call of the builtin in InstanceofStub was not correctly protected with an internal frame leading to the return address being handled as a pointer during GC.

Marked the Instanceof stub as allowing stub calls (the RecordWriteStub was removed some days ago).

This issue was not caught by the assertion designed for this when debug mode is run with --debug-code (which out tests always does) as generating code for Abort set the allow stub calls flag to true. This has been fixed by restoring the allow stub calls flag correctly.
