abrown opened PR #1994 from widen to main:

After #1990 is merged, this change adds the remaining instructions necessary for passing all of the current SIMD spec tests. This implementation uses PALIGNR, PMOVSX* and PMOVZX* for lowering the Wasm SIMD widen instructions. It also adds a mechanism for merging lanes in the CDSL for calculating the various type conversions (e.g. i16x8 is widened to i32x4).
