Anton Korobeynikov 090323aee5 Split A8/A9 itins - they already were too big.

Anton Korobeynikov a248becd6c Fix itins for VABA

Anton Korobeynikov 7d4fad5942 VHADD differs from VHSUB at least on A9 - the former reads both operands in the second cycle, while the latter reads second operand in first cycle. Introduce new itin classes to catch this behavior. Whether this is true for A8 as well is WIP.

Anton Korobeynikov 2063705d91 Define new itin classes for ARM <-> VFP reg moves to distinguish from NEON ops. Define proper scheduling itinerary for them on A9. A8 TRM does not specify latency for them at all :(

Anton Korobeynikov 4c1da0f82a Add new itin classes for FP16 <-> FP32 conversions and make uise of them for A9.

Anton Korobeynikov baeb210be7 Make use of new reserved/required scheduling stuff: introduce VFP and NEON locks to model domain cross stalls precisly.

Evan Cheng 4e712de541 Latency information for ARM v6. It's rough and not yet hooked up. Right now we are only using branch latency to determine if-conversion limits.
