The JVM opcodes, access flags and array type codes. This interface does not define all the JVM
opcodes because some opcodes are automatically handled. For example, the xLOAD and xSTORE opcodes
are automatically replaced by xLOAD_n and xSTORE_n opcodes when possible. The xLOAD_n and
xSTORE_n opcodes are therefore not defined in this interface. Likewise for LDC, automatically
replaced by LDC_W or LDC2_W when necessary, WIDE, GOTO_W and JSR_W.
