cdhash_cmp: can take rational literals
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]

cdhash_cmp: can also take complex
There are complex literals `123i`, which can also be a case condition.

cdhash_cmp: recursively apply
For instance a rational's numerator can be a bignum. Comparison using
C's == can be insufficient.
