Some shader manager changes, to avoid a shader be re-generated / re-compiled again, and again, if it is failed at the first time. There used to be cases that a vertex shader was failed, and Dolphin tried to generate/compile it forever, and caused the entire game slow down. It maybe not the case anymore after recent changes.
