1. Spell SectionFlags::Writeable as "Writable".
2. Add predicates for deriving SectionFlags from SectionKinds.
3. Sink ELF-specific getSectionPrefixForUniqueGlobal impl into
ELFTargetAsmInfo.
4. Fix SectionFlagsForGlobal to know that BSS/ThreadBSS has the
BSS bit set (the real fix for PR4619).
5. Fix isSuitableForBSS to not put globals with explicit sections
set in BSS (which was the reason #4 wasn't fixed earlier).
6. Remove my previous hack for PR4619.

The later doesn't depend on any crazy LLVM IR stuff, and this
pulls the concatenation of prefix with GV name (the root problem behind
PR4584) out one level.

a new getSectionForMergableConstant hook. This removes one dependence
of TAI on Type, and provides the hook with enough info to make the
right decision based on whether the global has relocations etc.

into DarwinTargetAsmInfo.cpp. The remaining differences should
be evaluated. It seems strange that x86/arm has .zerofill but ppc
doesn't, etc.

UsedDirective for some symbols in llvm.used into
Darwin-specific code. I've decided LessPrivateGlobal
is potentially a useful abstraction and left it in
the target-independent area, with improved comment.
