* FIX #1434
Rewrite rules for RealFrac methods with sized Int and Word targets.
For all types whose range is contained in Int's range, there are now
rewrite rules for properFraction, truncate, floor, ceiling and round
from Double and Float, going through the specialised methods for Int.
Unfortunately, we can't have a rewrite rule for Word.
