If you just have a magic block of instructions you want to stick
somewhere, a module-level inline asm may be the easiest way. If
you have higher-level language code you want to stick somewhere,
you should probably create a new Function (and/or MachineFunction)
that can be "called", so that it plays nicely with the rest of
the compiler.
