[wasm][interpreter] Clear thread in wasm flag on exceptional return

this, we now clear the flag during exceptional returns if it is set.

    git pull origin
    gclient sync

For fetching all branches, add the following into your remote configuration in .git/config:

    fetch = +refs/branch-heads/*:refs/remotes/branch-heads/*
    fetch = +refs/tags/*:refs/tags/*
