Peter Klausler 9d0043a35f [flang] Refactor "unused"/"used without definition" warnings (#179539) ...

I'm emitting a false warning "used without definition" warning for
variable cited in an inquiry intrinsic (e.g. LBOUND), and failing to
emit an "unused local" warning for allocatables that only appear in
ALLOCATE statements.

This patch makes the analysis more context-aware by rewriting it in
terms of typed expression traversal, and moves the analysis part into
Evaluate/check-expression.cpp from Semantics/expression.cpp.
