tools/memory-model: Convert underscores to hyphens
Typical cat-language code uses hyphens for word separators in identifiers, but several LKMM identifiers use underscores instead. This commit therefore converts underscores to hyphens in the .bell- and .cat-file identifiers corresponding to smp_mb__before_atomic(), smp_mb__after_atomic(), and smp_mb__after_spinlock().
