target-arm: Move Neon VZIP to helper functions

Move the implementation of the Neon VUZP unzip instruction from inline
code to helper functions. (At 50+ TCG ops it was well over the
recommended limit for coding inline.) The helper implementations also
give the correct answers where the inline implementation did not....

Move the implementation of the Neon VUZP unzip instruction from inline

recommended limit for coding inline.) The helper implementations also

instruction).

target-arm: Use standard FPSCR for Neon half-precision operations

The Neon half-precision conversion operations (VCVT.F16.F32 and
VCVT.F32.F16) use ARM standard floating-point arithmetic, unlike
the VFP versions (VCVTB and VCVTT).

target-arm: Fix VQMOVUN Neon instruction.

VQMOVUN does a signed-to-unsigned saturating conversion. This is
different from both the signed-to-signed and unsigned-to-unsigned
conversions already implemented, so we need a new set of helper
functions (neon_unarrow_sat*)....

ARM: add neon helpers for VQSHLU

Add neon helper functions to implement VQSHLU, which is a
signed-to-unsigned version of VQSHL available only as an
immediate form.

target-arm: convert NEON VZIP/VUZP/VTRN helper functions to pure TCG

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....

Implement (very) basic Thumb2-EE support. This doesn't actually implement
EE state, just the associated system coprocessor registers. It is sufficient
to keep OS setup and context switching code happy.
