120a0eb3ea23a5b06fae2f3daebd46a4035864cf target/arm: Implement VFP fp16 for VFP_BINOP operations
Implmeent VFP fp16 support for simple binary-operator VFP insns VADD,
VSUB, VMUL, VDIV, VMINNM and VMAXNM:
* make the VFP_BINOP() macro generate float16 helpers as well as
float32 and float64
* implement a do_vfp_3op_hp() function similar to the existing
do_vfp_3op_sp()
* add decode for the half-precision insn patterns
Note that the VFP_BINOP macro use creates a couple of unused helper
functions vfp_maxh and vfp_minh, but they're small so it's not worth
splitting the BINOP operations into "needs halfprec" and "no
halfprec" groups.
