We should add some text to help people port programs using these old
opcodes to whatever the new way is, if it isn't there already.

> ! The double-precision shift instructions @code{shld} and @code{shrd} are
> ! removed from @code{djasm} because they violate the established convention
> ! of using the @code{b}, @code{w}, or @code{d} mnemonic suffix to specify
> ! the memory operand size.  (The result is that they use up two mnemonics
> ! that should have been reserved for the basic shift/rotate instructions.)
