Most of the mjsunit/wasm/table-copy.js tests have been ported to cctests, so they can be tested with all execution tiers. Bug: v8:8965 Change-Id: I448719be30a4b2bddb9e2cffb4c74d3134db2f50 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1529548 Commit-Queue: Ben Smith <binji@chromium.org> Reviewed-by: Andreas Haas <ahaas@chromium.org> Cr-Commit-Position: refs/heads/master@{#60396}
