Emit the "[loop]" attribute on "for" and "while" so that FXC does not attempt to unroll them. This is to work around an FXC bug where it fails to unroll loops with gradient operations. FXC ostensibly unrolls such loops because gradient operations require uniform control flow, and loops that have varying iterations may possibly not be uniform. Tint will eventually validate that control flow is indeed uniform, so forcing FXC to avoid unrolling in these cases should be fine.
