Reintroduces the scalable vector IR type from D32530, after it was reverted a couple of times due to increasing chromium LTO build times. This latest incarnation removes the walk over aggregate types from the verifier entirely, in favor of rejecting scalable vectors in the isValidElementType methods in ArrayType and StructType. This removes the 70% degradation observed with the second repro tarball from PR42210.
