58a99d4e - [CodeGen][NPM] Update dominator tree and post dominator tree consistently (#173485)

[CodeGen][NPM] Update dominator tree and post dominator tree consistently (#173485) These passes run "RenumberBlocks()" on Machine function which renders the dominator tree analyses in the cache stale (though passes may not change anything structurally). we need to update the block numbers in the cached analyses if we are to return PreservedAnalysis::all(). This is not an issue with legacy PM since none of these passes preserve dominator tree analyses anyway.
