Thomas Lively aa67735fd2 [WebAssembly] Omit wrap on i64x2.{shl,shr*} ISel when possible ...

Summary:
Since the WebAssembly SIMD shift instructions take i32 operands, we
truncate the i64 operand to <2 x i64> shifts during ISel. When the i64
operand is sign extended from i32, this CL makes it so the sign
extension is dropped instead of a wrap instruction added.
