Recognize Shift(vec, vec(8)) and replace with Shift(vec, 8)

	public static Vector<uint> Method(Vector<uint> v)
	{
		return Method<Struct>(v);
	}

	public static Vector<uint> Method<TStruct>(Vector<uint> v) where TStruct : IInterface
	{
		return v << TStruct.Shift;
	}

	public interface IInterface
	{
		public static abstract int Shift { get; }
	}

	public struct Struct : IInterface
	{
		public static int Shift => 8;
	}

Actual codegen:

C.Method(System.Numerics.Vector`1<UInt32>)
    L0000: vzeroupper
    L0003: vmovups ymm0, [rdx]
    L0007: mov eax, 8
    L000c: vmovd xmm1, eax
    L0010: vpslld ymm0, ymm0, xmm1
    L0014: vmovups [rcx], ymm0
    L0018: mov rax, rcx
    L001b: vzeroupper
    L001e: ret

Expected codegen:

C.Method(System.Numerics.Vector`1<UInt32>)
    L0000: vzeroupper
    L0003: vmovups ymm0, [rdx]
    L0007: vpslld ymm0, ymm0, 8
    L000c: vmovups [rcx], ymm0
    L0010: mov rax, rcx
    L0013: vzeroupper
    L0016: ret
