clang: Remove -Wno-c++11-compat.

clang: Remove -Wno-c++11-compat.

It has been removed from -Wall in clang r143248 (Oct 2011), so
there's no need to explicitly disable it. No behavior change.

Probably worth to try and turn this flag _on_. It looks like WTF/nullptr.h
WebKit doesn't handle the "compiler knows nullptr, but c++ library doesn't
provide std::nullptr_t" case correctly, and we might have to fix a few narrowing
conversions to make that pass. Not today.

It's a second try, previously, step "browser_tests" failed.
