[wave] Hooks not called for expanding specific predefined macros

[Tamas Berghammer <berghammer.tamas@…>]

Non of the preprocessor hook is called during the expansion of the following predefined macros: __LINE__, __FILE__, __INCLUDE_LEVEL__.

This is because the expansion of these macros are handled with a specific code path which skips the hooks.

Expected behavior:

• expanding_object_like_macro hook is called before the expansion
• expansion happens based on the return value from the hook
• expanded_macro hook is called after the expansion
