Diagnose when trying to assemble conditional FP16 vmovx and vins
This patch makes GAS emit a warning when trying to assemble the Armv8.2
FP16 instructions VMOVX and VINS with condition codes. The Armv8-A
Reference Manual specifies these instructions without conditional codes
and says that if they are found in an IT block that they are CONSTRAINED
UNPREDICABLE.
gas/ChangeLog:

* config/tc-arm.c (do_neon_movhf): If conditional error out when in arm
mode and emit warning in thumb mode.
