Unsuffixed float literals are currently treated as f32, but will shortly become AbstractFloat. To keep tests behaving identically to how they are currently, change all float literals to explicitly use the f32 '_f' suffix. Bug: tint:1504 Change-Id: I2a00725ee1b34a6efbe15ac4ba438c00c4416dd8 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/89402 Reviewed-by: Dan Sinclair <dsinclair@chromium.org> Commit-Queue: Ben Clayton <bclayton@google.com> Kokoro: Kokoro <noreply+kokoro@google.com>
