Add option to give each usage of a data constructor its own info table

The `-fdistinct-constructor-tables` flag will generate a fresh info
table for the usage of any data constructor. This is useful for
debugging as now by inspecting the info table, you can determine which
usage of a constructor caused that allocation rather than the old
situation where the info table always mapped to the definition site of
the data constructor which is useless.

In conjunction with `-hi` and `-finfo-table-map` this gives a more fine
grained understanding of where constructor allocations arise from in a
program.
