Rename helper flags to the new ones. This is purely a mechanical change,
it's possible to use better flags by looking at the helpers.

Implement abs_i32 inline (with movcond) rather than using a helper
function.

Use the TCG operation to do Neon 64 bit negations rather than calling
a helper routine for it.

Now that the movcond TCG op is available, it's possible to replace
shl and shr helpers by TCG code. The code generated by TCG is slightly
longer than the code generated by GCC for the helper but is still worth
it as this avoid all the consequences of using an helper: globals saved
back to memory, no possible optimization, call overhead, etc.

Now that the setcond TCG op is available, it's possible to replace
add_cc and sub_cc helpers by TCG code. The code generated by TCG is
actually very close to the one generated by GCC for the helper, and
this avoid all the consequences of using an helper: globals saved back
to memory, no possible optimization, call overhead, etc.

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.

All the users of cpu_arm_set_cp_io have been converted, so we

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.

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.

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.
