[X86][AVX] Fold loads + splats into broadcast instructions
On AVX and AVX2, BROADCAST instructions can load a scalar into all elements of a target vector.
This patch improves the lowering of 'splat' shuffles of a loaded vector into a broadcast - currently the lowering only works for cases where we are splatting the zero'th element, which is now generalised to any element.
Fix for PR23022
