Do compile/link unlocked if not threaded (but thread-safe) If GL_KHR_parallel_shader_compile is not supported, or it is not used to do threaded compilation and link, this change lets the compile and link jobs be done after releasing the share group lock. With multithreaded/multi-context applications, this allows the other context (typically the main context) to make progress in the meantime. A typical scenario where this optimization matters is games seamlessly loading a new area of the game and performing compilation and link in a separate context. Before this change, the game would stutter as the compile/link jobs prevent the main thread from drawing anything. With this change, the hitching is removed.
