Architecturally, Neon FP16 operations use the "standard FPSCR" like all other Neon operations. However, this is defined in the Arm ARM pseudocode as "a fixed value, except that FZ16 (and AHP) follow the FPSCR bits". In QEMU, the softfloat float_status doesn't include separate flush-to-zero for FP16 operations, so we must keep separate fp_status for "Neon non-FP16" and "Neon fp16" operations, in the same way we do already for the non-Neon "fp_status" vs "fp_status_f16". Add the extra float_status field to the CPU state structure, ensure it is correctly initialized and updated on FPSCR writes, and make fpstatus_ptr(FPST_STD_F16) return a pointer to it.
