[patch] Remove unused parameter from complete_type_or_diagnostic

[Volker Reichelt]

The function complete_type_or_diagnostic in cp/typeck.c is only
called via the macro complete_type_or_else with the third parameter
always being 0.

The following patch removes this useless last parameter of
complete_type_or_diagnostic. By renaming the function to
complete_type_or_else we get rid of the macro, too.

Bootstrapped and regtested on i686-pc-linux-gnu.

Ok for mainline?

Regards,
Volker
