I think the answer is "usually not".  C is an exception, as you
noted.  So is Espol, the OS writing language on Burroughs mainframes.

I'd also exclude systems (like PDP11s) which have a program overlay
mechanism -- that too of course is self-modifying code, and generally
would be supported with any language used on that system, high level
languages included.
