This assembler instruction compiles fine:

    inc [EAX];

However, the code makes no indication of the memory size. DMD just assumes
"byte ptr".

The severity of this is increased by that at least one other inline assembler
(Delphi's) makes an incompatible assumption (it assumes "dword ptr").

I suggest that this behavior is made deprecated, and code compiled without -d
should be forced to disambiguate operand size.
