Dereference pointers when generating getters for pointer variables.
Otherwise, the managed instance would point to the pointer itself
rather than the object at the native instance's address.
- Expression generation for `ConstructorReference` now also recursively
calls `VisitExpression` for the argument if only one argument is
detected. This allows correct overload generation for functions taking
a variable as the default parameter value.
- Default parameters of pointer-to-enumeration types are now correctly
generated similar to primitive types.
* CSharpExpressionPrinter: Recurse into operands
Recursively call `VisitExpression` on the LHS and RHS of a binary
operator expression. This fixes the generation for complex default
parameters involving things other than two enumeration members.
* CSharpSources: Use `const` when possible
Generate `const` instead of `static` members when possible.
This allows generated members to be used when compile-time constants are
required, such as default parameters.
