Allow upgrade from OTP 17.1 to newer.

This fixes a bug introduced in f11aabdc9fec593c31e6c4f3fa25c1707e9c35df where
filelib:eval_read_file_info/2 was made to use file:read_link_info/1 to never
follow symlinks. This fixed wildcard/1 but broke every other function using
eval_read_file_info/2.

This ticket is about records in Erlang code, and when to check the
fields against the (optional) types given when defining records.

Dialyzer operates on the Erlang Core format, where there are no trace
of records. The fix implemented is a Real Hack:

Given the new option 'dialyzer' erl_expand_records marks the line
number of records in a way that is undone by v3_core, which in turn
inserts annotations that can be recognized by Dialyzer.

The fallback to latin-1 encoding would not work if the invalid
UTF-8 characters occurred in a skipped branch in an -ifdef/-ifndef.
