This effectively reverts commit 2a3f75b4 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.) Signed-off-by: NPeter Maydell <peter.maydell@linaro.org>

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. Signed-off-by: NPeter Maydell <peter.maydell@linaro.org>

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.

Correct the argument and return types for the float<->int conversion helper functions so that integer arguments and return values are declared as uint32_t/uint64_t, not float32/float64. This allows us to remove the hand-rolled functions which were doing bitwise copies between the types via unions.

The neon_trn_u8, neon_trn_u16, neon_unzip_u8, neon_zip_u8 and neon_zip_u16 helpers used fixed registers to return values. This patch replaces that with TCG code, so T0/T1 is no longer directly used by the helper functions. Bugs in the gen_neon_unzip register load code were also fixed.
