It was kind of a joke, but it's entirely possible.  You could write a
compile-time x86 assembler that would take a string and turn it into a
series of bytes.  Or simpler, just convert those instructions which
DMD doesn't know about into bytes, and leave the other instructions
alone.  You can then mix that into an assembly statement.

It's probably incredibly impractical for all but the simplest cases
but keep in mind that the compiler _is_ Turing-complete.
