Function instr_build 

pub unsafe extern "C" fn instr_build(
    drcontext: *mut c_void,
    opcode: c_int,
    num_dsts: c_int,
    num_srcs: c_int,
) -> *mut instr_t

Convenience routine: calls

• instr_create(dcontext)
• instr_set_opcode(opcode)
• instr_set_num_opnds(dcontext, instr, num_dsts, num_srcs)

and returns the resulting instr_t.
