-femit-struct-debug-reduced/baseonly debug info

[Evgeny Gavrin]

Behavior of the compiler does not match the documentation.

The following "-femit-struct-debug-detailed=ind:ord:base" means that debug info should be emitted for structs used indirectly and declared in file that matches the base name of the compilation file (test.c/test.h).

So, in the particular case, when struct is used indirectly in test.c and declared in test-nonbase.h - info on structs shouldn't be emitted.

In case of, "-femit-struct-debug-detailed=ord:base" - it works correctly and emits nothing.

I think that there is a bug in interpretation of optional parameters.
