* Implement storage buffer operations using new Load/Store instruction * Extend GenerateMultiTargetStorageOp to also match access with constant offset, and log and comments * Remove now unused code * Catch more complex cases of global memory usage * Shader cache version bump * Extend global access elimination to work with more shared memory cases * Change alignment requirement from 16 bytes to 8 bytes, handle cases where we need more than 16 storage buffers * Tweak preferencing to catch more cases * Enable CB0 elimination even when host storage buffer alignment is > 16 (for Intel) * Fix storage buffer bindings * Simplify some code * Shader cache version bump * Fix typo * Extend global memory elimination to handle shared memory with multiple possible offsets and local memory
