[PATCH v2 36/45] target/arm: Implement fp16 for Neon float-integer VCVT

2020-08-28 Thread Peter Maydell
Convert the Neon float-integer VCVT insns to gvec, and use this to implement fp16 support for them. Note that unlike the VFP int<->fp16 VCVT insns we converted earlier and which convert to/from a 32-bit integer, these Neon insns convert to/from 16-bit integers. So we can use the existing vfp conve
