3b445f14f8 X64 tweaks. 
Use movapd instead of movsd to move between xmm registers. Avoids partial
register writes and potential stalls.

Use xorps instead of xorpd to zero a register. Same effect and latency, but
one byte smaller.

cc782be64e Support string add in crankshaft: 
o The type recording binary stub got a new type for string + string.

o Added HStringAdd and LStringAdd based on the new type info.

o Started using HValue types to avoid unneccesary checks.

ce5500e639 X64: Convert HeapNumbers that contain valid smi values to smis in binop-stub. 
When the TypeRecordingBinaryOpStub expect smi values as input, they might
sometimes come as HeapNumbers. The transition code will detect the heap numbers
as holding values that are valid smi values, and will not change the expectations.
However, the stub didn't handle HeapNumbers and always tried to transition again.

a224db3a50 X64: Optimize access to external references. 
Access to an ExternalReference in non-serializable code will try to use
an offset relative to the root-array register.
Since the root-array is in the Heap object, and the Heap object is in
the Isolate object, there's a good chance that any external data field
is within a 32-bit offset of the root array register.
It falls back on the original behavior if the serializer is enabled,
if the root register isn't initialized or if the offset is not representable
as a 32-bit value.

061fa8be11 Add the possibility for a code stub to be non-movable 
Non-moveable code-stube are allocated in large object space. They are only required on ARM where the different C-entry stubs are required to never move.

This gets rid of pre-computing these stubs and hope that they never move. Also for crankshaft the C-entry stub which saved doubles is not generated in the snapshot so it ends up being generated at runtime and potentially move.
