The reasons for HotSpot (at least) not already being on C++14 (cost of
switching over the Solaris Studio based platform) also apply to C++11.
A big part of the work involves dealing with changes to the compilation
model, the runtime libraries, and the ABI, all of which are part of
Solaris Studio's transition from C++98 to C++11.
