[google gcc-4_7, integration] Build more of libstdc++ with frame pointers

[Paul Pluzhnikov]

Greetings,

Google ref b/8187733

Build libstdc++-v3/src/c++11/debug.cc with -fno-omit-frame-pointer, so
frame-based unwinder can step through it.

Tested: bootstrap build and verified debug.cc is built with
-fno-omit-frame-pointer.

Ok for google/gcc-4_7 and google/integration?

Thanks,
