4a9a539ffb target-arm: Remove remaining old cp15 infrastructure
There are now no uses of the old cp15 infrastructure,
so it can be deleted.

e8070a23a8 target-arm: Remove old cpu_arm_set_cp_io infrastructure
All the users of cpu_arm_set_cp_io have been converted, so we
can remove it and the infrastructure it used.

4b6a83fb0c target-arm: initial coprocessor register framework
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.

02da0b2d71 Revert "target-arm: Use global env in neon_helper.c helpers"
This effectively reverts commit 2a3f75b42a
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.)

aa47cfdd17 target-arm: Pass fp status pointer explicitly to neon fp helpers
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.

ae1857eca2 target-arm: Make VFP binop helpers take pointer to fpstatus, not CPUState
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 947a2fa21b,
returning the iwmmxt helpers to passing env in as a parameter.

5500b06cb5 target-arm: Use correct float status for Neon int-float conversions
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.
