Title: (PUP-3401) Fix type calculations of "all Patterns"

The type calculator did not correctly compute assignability for
a non parameterized Pattern. Such a Pattern is equal to "any string",
and is thus assignable from any other Pattern, Enum or String.

This was missing in the calculator and this resulted in Pattern neither
being equal to, less than, or greater than parameterized patterns.
