There was a problem hiding this comment.
Kind of weird to have a void return on a function called get, but I guess that's not directly related to this PR.

fuzz_shell.jsalready allows linking in a second file from JS. This does the same forwasm-opt's
--fuzz-exec-beforefunctionality.To do that, track linked instances in execution results, and link and run
a second module there, if provided.
This will be useful in fuzzing cross-module code, which we atm do in
V8, but running in our interpreter will use our own assertions.
