The PMOVZXWD family of functions had patterns extends narrow vector types to wide vector types.
It had patterns for zext-loading and extending. This commit adds patterns for loading a wide type, performing a bitcast,
and extending. This is an odd pattern, but it is commonly used when writing code with intrinsics.
