Report spec discrepancy on mismatching lists
This patch enables Dialyzer to detect cases where a function has a specification
for a return type containing some list with elements different than the ones
Dialyzer's own algorithm can infer e.g. a function specified to return [atom()]
when actually [[atom()]] is returned.
Previously Dialyzer remained silent, under normal operation, seeing that these
two types have the empty list as a common element, so they were not 'completely
irrelevant'.
