Ryan Houdek 6646a5cc72 OpcodeDispatcher: Fixes SHLD by 16 behaviour ...

We were assuming that SHLD undefined behaviour matches SHL, but the
specification actually changes a `ge` comparison to `gt`, which means a
shift of 16 isn't UB!

Thanks to the impeccable @OFFTKP in #5842 for bringing this up as it took a bit
for me to figure out what was actually wrong here. I modified their
unittest to cover more just to ensure we don't break it.
