645c0d50 - [AArch64][GlobalISel] Ensure we have a insert-subreg v4i32 GPR pattern (#142724)

[AArch64][GlobalISel] Ensure we have a insert-subreg v4i32 GPR pattern (#142724) This is the GISel equivalent of scalar_to_vector, making sure that when we insert into undef we use a fmov that avoids the artificial dependency on the previous register. This adds v2i32 and v2i64 patterns too for similar reasons.
