  Changed paths:

    M clang/test/Driver/wasm-toolchain.c

  Log Message:
  -----------
  [WebAssembly] -pthread implies -target-feature +sign-ext

Summary:
The sign extension proposal was motivated by a desire to not have
separate sign-extending atomic operations, so it is meant to be
enabled when threads are used.
