[PATCH][AArch64] Add combine pattern for storing lane zero of a vecto

Hi all, Consider the code: typedef long long v2di __attribute__ ((vector_size (16))); void store_laned (v2di x, long long *y) { y[0] = x[1]; y[3] = x[0]; } AArch64 GCC will generate: store_laned: umovx1, v0.d[0] st1 {v0.d}[1], [x0] str x1, [x0, 24]
