[SveEmitter] Add SVE tuple types and builtins for svundef.
This patch adds new SVE types to Clang that describe tuples of SVE vectors. For example `svint32x2_t` which maps to the twice-as-wide vector `<vscale x 8 x i32>`. Similarly, `svint32x3_t` will map to `<vscale x 12 x i32>`. It also adds builtins to return an `undef` vector for a given SVE type.
