There isn't any fundamental reason why you couldn't compile a piece of
Fortran and JIT the resulting IR; IR is IR, no matter how you get it.
Given the architecture of gcc, though, you'd probably have to run
dragonegg gfortran as a separate process.  And you'd need to come up
with some trickery to make the Fortran libs available for the
application.  All relatively straightforward, but I don't see the
point.
