    d: Fix undefined reference to pragma(inline) symbol (PR106563)

    Functions that are declared `pragma(inline)' should be treated as if
    they are defined in every translation unit they are referenced from,
    regardless of visibility protection.  Ensure they always get
    DECL_ONE_ONLY linkage, and start emitting them into other modules that
    import them.

            PR d/106563

    gcc/d/ChangeLog:

            * decl.cc (DeclVisitor::visit (FuncDeclaration *)): Set semanticRun
            before generating its symbol.
            (function_defined_in_root_p): New function.
            (function_needs_inline_definition_p): New function.
            (maybe_build_decl_tree): New function.
            (get_symbol_decl): Call maybe_build_decl_tree before returning
symbol.
            (start_function): Use function_defined_in_root_p instead of inline
            test for locally defined symbols.
            (set_linkage_for_decl): Check for inline functions before private
or
            protected symbols.
