Log Message:
-----------
make available to HLLs two new derived hash key types - PMC_ptr and STRING_enc

By default key types are unavailable to HLLs because they are "dangerous". However, these
types are derived from PMC and STRING key types, differing only in comparison function.

Also, simplify chained if-else into a switch.
