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).

softfloat: Add float16 type and float16 NaN handling functions

Add a float16 type to softfloat, rather than using bits16 directly.
Also add the missing functions float16_is_quiet_nan(),
float16_is_signaling_nan() and float16_maybe_silence_nan(),
which are needed for the float16 conversion routines....

target-arm: Fix 32 bit signed saturating narrow

The returned value when doing saturating signed 64->32 bit
conversion of a negative number was incorrect due to a missing cast.

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*)....

target-arm: Fix decoding of Thumb preload and hint space

Refine the decoding of the Thumb preload and hint space, so we
UNDEF on the patterns that are supposed to UNDEF rather than NOP.
We also move the tests for this space earlier, so we don't emit
harmless but unnecessary address generation code for preload...
