Subject: ARM: Implement VCVT to 16 bit integer using new softfloat routines
X-Git-Tag: v0.14.0-rc0~350^2

ARM: Implement VCVT to 16 bit integer using new softfloat routines

Use the softfloat conversion routines for conversion to 16 bit
integers, because just casting to a 16 bit type truncates the
value rather than saturating it at 16-bit MAXINT/MININT.
