  [reland][Alignment] Use Align in MCStreamer emitZeroFill/emitLocalCommonSymbol

Before performing this change, I checked that `ByteAlignment` was never `0` inside `MCAsmStreamer:emitZeroFill` and `MCAsmStreamer::emitLocalCommonSymbol`.
I believe it is NFC as `0` values are illegal in `emitZeroFill` anyways, `Log2(ByteAlignment)` would be undefined.
And currently, all calls to `emitLocalCommonSymbol` are provably `>0`.
