Factor out machinery for forming int type literals. (#4616)

Browse Source 
Use it in the remaining few places where we currently hardcode `i32`: as
the index type in array indexing, as the type for literals in `if`
expressions, and as a valid return type for `Run`.

In preparation for changing `Core.Int` to be a class.
