Cleanup handling of .zerofill on darwin:

1. TargetLoweringObjectFileMachO should decide if something
goes in zerofill instead of having every target do it.
2. TargetLoweringObjectFileMachO should assign said symbols to

right section.
3. Since all zerofill stuff goes through mcstreamer anymore,
MAI can have a bool "haszerofill" instead of having the textual
directive to emit.
