This CL introduces support for writing inputs to wasm tests in wat format. This will allow removing dependencies on opaque binary resources that can't be regenerated without changing hardcoded offsets in all tests. Referencing binary and/or source file offsets will now be possible through special comments left in the wat source. Bug: 1328729 Change-Id: I6369c86ca57860fd9803b894797f63c36c65d554 Reviewed-on: https://chromium-review.googlesource.com/c/devtools/devtools-frontend/+/3666419 Commit-Queue: Philip Pfaffe <pfaffe@chromium.org> Reviewed-by: Simon Zünd <szuend@chromium.org>
