b16df72475 Improve our type feedback by recogizining never-executed IC calls for binary operations.
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.

65f98b1e7a Fix issue 962.
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.

38343f79fa Increase the size of the max object that can be new space allocated.
This is neutral on in-browser SunSpider, but beneficial on other
things, and is likely to lower memory use by collecting earlier.

48d884de48 ARM: Fix heap number allocation in lithium-codegen-arm that assumed
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.

eb8e1d9d0e Change test script to make it easy to run crankshaft tests on ARM and
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. :)

e0d3f6afdf Be more careful about exiting inlined functions in a test context.
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.
