Add `SemanticsVisitor` as the visitor class to perform statement
semantics checks. Its template parameters are "checker" classes
that perform the checks. They have `Enter` and `Leave` functions
that are called for the corresponding parse tree nodes (`Enter`
before the children, `Leave` after). Unlike `Pre` and `Post` in
visitors they cannot prevent the parse tree walker from visiting
child nodes.
Existing checks have been incorporated into this framework:
- `ExprChecker` replaces `AnalyzeExpressions()`
- `AssignmentChecker` replaces `AnalyzeAssignments()`
- `DoConcurrentChecker` replaces `CheckDoConcurrentConstraints()`
Adding a new checker requires:
- defining the checker class:
- with BaseChecker as virtual base class
- constructible from `SemanticsContext`
- with Enter/Leave functions for nodes of interest
- add the checker class to the template parameters of `StatementSemantics`
Because these checkers and also `ResolveNamesVisitor` require tracking
the current statement source location, that has been moved into
`SemanticsContext`. `ResolveNamesVisitor` and `SemanticsVisitor`
update the location when `Statement` nodes are encountered, making it
available for error messages.
`AnalyzeKindSelector()` now has access to the current statement through
the context and so no longer needs to have it passed in.
Test `assign01.f90` was added to verify that `AssignmentChecker` is
actually doing something.
