Title: gh-3216 Add more info to int/string in IR

Adding signed/unsigned and size+precision to numeric types
as well as string length, when known, to string types.

This change triggered a major change to refactor ITypeInfo
and move checks inside the class. Here's the first step,
which only moves the code in, leaving the global functions
still in place.

A subsequent commit will replace all calls to those functions
by their direct member function calls.
