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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77085 91177308-0d34-0410-b5e6-96231b3b80d8
