[AArch64, Patch] Generate MLA when multiply + add vector by scalar

Hi all, This merges vector multiplies and adds into a single mla instruction when the multiplication is done by a scalar. Currently, for the following: typedef int __attribute__((vector_size(16))) vec; vec mla0(vec v0, vec v1, vec v2) { return v0 + v1 * v2[0]; }
