bpf: refactor inst patterns with better inheritance
Arithmetic and jump instructions, load and store instructions are sharing
the same 8-bit code field encoding,
A better instruction pattern implemention could be the following inheritance
relationships, and each layer only encoding those fields which start to
diverse from that layer. This avoids some redundant code.
InstBPF -> TYPE_ALU_JMP -> ALU/JMP
InstBPF -> TYPE_LD_ST -> Load/Store
