`parser::AllocateObject` and `parser::PointerObject` can be represented
as typed expressions once analyzed. This simplifies the work for parse-tree
consumers that work with typed expressions to deal with allocatable and
pointer objects such as lowering.

Changes:

- Add a `mutable TypedExpr typedExpr` field to `parser::PointerObject` and `parser::AllocateObject`.
- In `semantics::NullifyChecker`, set the `parser::PointerObject` typedExpr after expression analysis.
- In `semantics::DeallocateChecker`, set the `parser::AllocateObject` typedExpr after expression analysis.
- In `semantics::AllocateChecker`, set the `parser::AllocateObject` typedExpr after expression analysis.
