[LLVMdev] C++14 support for shared_mutex

[David Majnemer]

The most reliable way would be to get your build system to try to compile
source code which includes <shared_mutex> and then instantiates
shared_mutex<> with a plausible type.  Anything else would be pretty
speculative as C++17 isn't even finished yet and it is possible, although
pretty unlikely IMO, for the feature to be removed.
