[patch] Fix mismatched #pragma GCC visibility

[Rafael Ávila de Espíndola]

While trying to improve clang's handling of "#pragma GCC visibility" I
found out that libstdc++-v3/libsupc++/typeinfo looks like

#pragma GCC visibility push(default)
extern "C++" {
#pragma GCC visibility pop
}

Is that supposed to work or just happens to? If desired, the attached
patch moves the pop after the closing }.

        * libsupc++/typeinfo: Correctly match #pragma GCC visibility
        pop with #pragma GCC visibility push.

Cheers,
Rafael
