43734637 - [GlobalISel] Widen vector loads from aligned ptrs (#144309)

[GlobalISel] Widen vector loads from aligned ptrs (#144309) If the pointer is aligned to more than the size of the vector, we can widen the load up to next power of 2 size, as SDAG performs. Some of the v3 tests are currently worse - those should be addressed in other issues.
