introduce a section kind for common linkage.  Use this to slightly
simplify and commonize some of the asmprinter logic for globals.

This also avoids printing the MCSection for .zerofill, which broke
the llvm-gcc build.

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
   the right MCSection, the asmprinters should just emit to the
   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.
