Instruction G_IS_FPCLASS had an operand that represented floating-point semantics of its first operand. It allowed types that have the same length, like `bfloat16` and `half`, to be distinguished. Unfortunately, it is not sufficient, as other operation still cannot distinguish such types. Solution of this problem must be more general, so now this operand is removed.
