leonardo.yvens 3d83fc914a Lazy numeric fallback. 
This refactoring tries to make numeric fallback easier to reason about.
Instead of applying all fallbacks at an arbitrary point in the middle
of inference, we apply the fallback only when necessary and only for
the variable that requires it, which for numeric fallback turns out to
be just casts.

The only visible consequence seems to be some error messages where
instead of getting `i32` we get `{integer}` because we are less eager
about fallback.

The bigger goal is to make it easier to integrate user fallbacks into
inference, if we ever figure that out.
