[ARM] Add ARMv8.3 VCMLA and VCADD instructions

[Szabolcs Nagy]

Add support for VCMLA and VCADD advanced SIMD complex number instructions.

The command line option is -march=armv8.3-a+fp16+simd for enabling all
instructions.

In arm-dis.c the formatting syntax was abused a bit to select between
0 vs 90 or 180 vs 270 or 90 vs 270 based on a bit value instead of
duplicating entries in the opcode table.
