Revert "target-arm: Use global env in neon_helper.c helpers"

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...

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...

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.

target-arm: Add helper function to generate code to get fpstatus pointer

Add and use a helper function which returns a TCGv which is a pointer
to the fp_status for either Neon or VFP operations.

Revert "target-arm: Use global env in iwmmxt_helper.c helpers"

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

target-arm: Fix compilation failure for 64 bit hosts

Use the correct _ptr aliases for manipulating the pointer to
the fp_status; this fixes a compilation failure on 64 bit hosts.

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...

target-arm: Signal InvalidOp for Neon GE and GT compares of QNaN

If the input to a Neon float comparison is a quiet NaN, the ARM ARM
specifies that we should raise InvalidOp if the comparison is GE or GT
but not for EQ. (Signaling NaNs raise InvalidOp regardless). This means...
