Correctly handle non-matching patterns against literal values
The pass sys_core_fold did not correctly handle non-matching patterns in code
such as:
0 = case <<>> of
<<>> -> 0;
a -> 1
end.
Function case_opt_lit/3 is rewritten in two passes to first remove any
non-matching clause and only then potentially remove the related patterns
in each clause.
