This patch aims to improve the codegen for vector loads involving the scalar_to_vector (load X) sequence. Initially, ld->mv instructions were used for scalar_to_vector (load X), so this patch allows scalar_to_vector (load X) to utilize: LXSD and LXSDX for i64 and f64 LXSIWAX for i32 (sign extension to i64) LXSIWZX for i32 and f64 Committing on behalf of Amy Kwan.
