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....

target-arm: Move Neon VUZP 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
fix the handling of the quadword version of the instruction....

target-arm: Correct conversion of Thumb Neon dp encodings into ARM

We handle Thumb Neon data processing instructions by converting them
into the equivalent ARM encoding, as the two are very close. However
the ARM encoding should have bit 28 set, not clear. This wasn't causing...

target-arm: Fix Neon VQDMLSL instruction

For VQDMLSL, negation has to occur after saturation, not before.

target-arm: Refactor handling of VQDMULL

Refactor the handling of VQDMULL so that it is dealt with in
its own if() case rather than together with the accumulating
instructions.

instruction).

arm: drop unused irq-related part of CPUARMState

These two fields were added as a part of ARMv7 support patch (back in
2007), were never used by any code, so can be dropped.

target-arm: Remove stray #include from middle of neon_helper.c

Remove a stray #include <stdio.h> from the middle of neon_helper.c:
it was harmless but pointless since we include stdio.h at the top
of the file anyway.

target-arm: Silence NaNs resulting from half-precision conversions

Silence the NaNs that may result from half-precision conversion,
as we do for the other conversions.

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).
