Implement new transform UnwindDiscardFunctions that replaces discard statements with setting a module-level bool, adds a check and return for this bool after every function call that may discard, and finally invokes a single function that executes a discard from top-level functions. Regenerated tests and remove HLSL ones that used to fail FXC because it had difficulty with discard.
