[X86] combineBROADCAST_LOAD - merge across chains (REAPPLIED) (#128209)
Remove the restriction when reusing wider BROADCAST_LOAD nodes that both nodes couldn't have uses of their load chains - use makeEquivalentMemoryOrdering to merge the chains instead. Reapplied - move makeEquivalentMemoryOrdering prior to the CombineTo call to ensure that the original node hasn't already been removed. Fixes asan use-after-poison error reported in #128380 / 50b0669.
