Fix performance regression in stream init. Regressed: https://chromium-review.googlesource.com/531798 This was because the std::stringstream constructor was being called every draw call, for the InfoLog of the dynamically recompiled shaders in the D3D back-ends. The constructor was allocating memory and freeing it on destruction. Instead use a lazy init for the std::stringstream in InfoLog like we do for Error.
