[PATCH] D21698: [OpenCL] Allow disabling types and declarations associated with extensions

I did profiling with valgrind for the cost of checking disabled types and declarations. For a typical program, time spent in checking disabled types and declarations are less than 0.1%, so this cost can be ignored.
