* Run the validator in the optimization fuzzers. The optimizers assumes that the input to the optimizer is valid. Since the fuzzers do not check that the input is valid before passing the spir-v to the optimizer, we are getting a few errors. The solution is to run the validator in the optimizer to validate the input. For the legalization passes, we need to add an extra option to the validator to accept certain types of variable pointers, even if the capability is not given. At the same time, we changed the option "--legalize-hlsl" to relax the validator in the same way instead of turning it off.
