fix(tests): update WAT used in tests (#249)

The excellent pre-existing test suite contains a lot of WAT files as
test-cases that seem to have older syntax in them.

The breakage is introduced because the current test suite runs stable,
latest and nightly versions of Rust while conducting tests. While the
rest of the Wasm toolchain (binaryen, wabt, etc) are hard-coded to versions that should
stay compatible with the WAT as they were written, the upstreaming of
various changes to Rust itself seems to be causing failures when using
the existing WAT for tests.

This PR updates the WAT (mostly operation renaming) that have changed
in order to get tests running again.
