dialyzer: Compact 'file' annotations in Core code
File annotations {file, File} in Core Erlang code is replaced by {file, FakeFile}, where FakeFile is "0", "1", ..., in order to save memory. When a warning message is created, FakeFile is translated to the original File (a bit awkward but easy to do). The Core code stored in ETS tables needs less space, but more important is that a less heap memory is used in the dataflow, warnings, and typesig phases, allowing more parallelism.
