Yes.  The JIT works by adding another slot to the bytecode object.
This slot holds the JIT-related data, like the compiled function.
So, things like advice don't affect the way it operates.

Writing this out made me remember another possible issue with the JIT:
because it works based on the bytecode object, when a closure is made
with make-byte-code, the JIT will compile each such closure separately.
It would be possible to, instead, have it compile a closure once; but at
some cost to the generated code.
