Allow users to ignore optimization changes
* Add a new flag, `-fignore-optim-changes`, allowing them to avoid
recompilation if the only changes are to the `-O` level or to
flags controlling optimizations.
* When `-fignore-optim-changes` is *off*, recompile when optimization
flags (e.g., `-fno-full-laziness`) change. Previously, we ignored
these unconditionally when deciding whether to recompile a module.
