[Bug translator/9719] New: improve type mismatch messages

[fche at redhat dot com]

During type inference/resolution during pass 2, a type mismatch
results in a message like 

semantic error: probe_1393 with type mismatch (long vs. string): identifier
'pid' at :30:3

which identifies only one site of the type mismatch (:30:3) but not the other.
The typeresolution_info::mismatch / ::resolved could be changed to track the
first resolution site (token) for a given expression tree, and then indicate
in the semantic error both the old and new tokens.
