Simplify AST transformations that need to find main
Share code for finding the main function from the AST between
InitializeVariables, DeferGlobalInitializers,
EmulateGLFragColorBroadcast and UseInterfaceBlockFields. This makes
InitializeVariables simpler in particular, as it doesn't need an AST
traverser anymore.
