Convert remaining helpers to AREG0 free mode: add an explicit
CPUState parameter instead of relying on AREG0.

Add an explicit CPUState parameter instead of relying on AREG0.
For easier review, convert only op helpers which don't return any value.

There are now no uses of the old cp15 infrastructure,
so it can be deleted.

Convert the THUMB2EE cp14 registers TEECR and TEEHBR to
use arm_cp_reginfo.

All the users of cpu_arm_set_cp_io have been converted, so we
can remove it and the infrastructure it used.

Initial infrastructure for data-driven registration of
coprocessor register implementations.
We still fall back to the old-style switch statements pending
complete conversion of all existing registers.

Implement the fused multiply-accumulate instructions (VFMA, VFMS,
VFNMA, VFNMS) which are new in VFPv4.

This effectively reverts commit 2a3f75b42ac255be09ec2939b96c549ec830efd3
so that we return to passing CPUState to helpers as an explicit parameter.
(There were a number of conflicts in target-arm/translate.c which had
to be resolved by hand so it is not a pure revert.)

Make the Neon helpers for various floating point operations take an
explicit pointer to the float_status they use, so they don't rely on
the global environment pointer any more. This also allows us to drop
the mul/sub/add helpers completely and just use the vfp versions.

Make the VFP binop helper functions take a pointer to the fp status, not
the entire CPUState. This will allow us to use them for Neon operations too.

This reverts commit 947a2fa21b61703802a660a938cabd7b3600ee79,
returning the iwmmxt helpers to passing env in as a parameter.

The Neon versions of int-float conversions must use the "standard FPSCR"
rather than the default FPSCR. Implement this by having the helper
functions take a pointer to the appropriate float_status value rather
than simply taking a pointer to the entire CPUState, and making
translate.c pass a pointer to vfp.fp_status or vfp.standard_fp_status
appropriately for whether the instruction being translated is Neon
or VFP.
