# 3same ext: 0b1111_110x_xxxx_xxxx_xxxx_1x0x_xxxx_xxxx
# VFP/Neon register fields; same as vfp.decode

# For VCMLA/VCADD insns, convert the single-bit size field
# which is 0 for fp16 and 1 for fp32 into a MO_* constant.
# (Note that this is the reverse of the sense of the 1-bit size
# field in the 3same_fp Neon insns.)
