The RegisterInfo descriptors for the convenience registers can specify an offset to be added to the offset as derived from

the value_regs field, which is useful for future expansion purposes.  As of now, we have:

    calculated_offset_of_eax = offset_of_rax + (offset_of_eax_from_the_descriptor which is 0)
