When -mattr=+alu32 passed to the disassembler, use decoder namespace for
32-bit subregister.
This is to disassemble load and store instructions in preferred B format
as described in previous commit:
w = *(u8 *) (r + off) // BPF_LDX | BPF_B
w = *(u16 *)(r + off) // BPF_LDX | BPF_H
w = *(u32 *)(r + off) // BPF_LDX | BPF_W
*(u8 *) (r + off) = w // BPF_STX | BPF_B
*(u16 *)(r + off) = w // BPF_STX | BPF_H
*(u32 *)(r + off) = w // BPF_STX | BPF_W
NOTE: all other instructions should still use the default decoder
namespace.
