cdhash_cmp: can take rational literals

Browse source 
Rational literals are those integers suffixed with `r`.  They tend to
be a part of more complex expressions like `123/456r`, but in theory
they can live alone.  When such "bare" rational literals are passed to
case-when branch, we have to take care of them.  Fixes [Bug #17854]
