Resubmit "Compile the D3D11 VS and PS on separate threads at GL link time" The original change caused a Chromium build break due to "__uncaught_exception" not being defined in concrt.h. This is because Chromium defines "_HAS_EXCEPTIONS=0" in its GYP, but ANGLE doesn't do this. This change defines "_HAS_EXCEPTIONS=0" in ANGLE's GYP to match Chromium, and refines it in ProgramD3D.cpp before including <future>.
