IR: Allow 32-bits for lines in debug location

Remove unnecessary restriction of 24-bits for line numbers in
`MDLocation`.

The rest of the debug info schema (with the exception of local
variables) uses 32-bits for line numbers.  As I introduce the
specialized nodes, it makes sense to canonicalize on one size or the
other.
