__scan_files_for_cr() should compile down to nothing if checkpoint/restart is disabled.
But, I think the spinlocks in fcheck_files() keep the compiler from figuring this out. So, instead if putting in some #ifdefs, use our new cr_enabled() helper. I've verified that this puts .text size back to where it was without the __scan_files_for_cr() call.
