460d51e0c0 make SectionKind be a first-class pod struct instead of just 
an enum.

b4fc419d83 this is (unfortunately) several changes mixed together: 
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.

b303504a56 make SectionKindForGlobal target independent, and therefore non-virtual. 
It's classifications now include elf-specific discriminators.  Targets
that don't have these features (like darwin and pecoff) simply treat
data.rel like data, etc.

f20f250b6f we already know the sectionkind when invoking SelectSectionForGlobal, 
pass it in instead of recomputing it.

298414ec18 remove the SelectSectionForMachineConst hook, replacing it with 
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.

has them.
