Rearrange all the SectionKinds and structure them into a hierarchical

group instead of a bunch of random unrelated ideas. Provide predicates
to categorize a SectionKind into a group, and use them instead of
getKind() throughout the code.
This also renames a ton of SectionKinds to be more consistent and
evocative, and adds a huge number of comments on the enums so that
I will hopefully be able to remember how this stuff works long from
now.

- This is a simplified mechanism which just looks up a target based on the

- Remove getClosestStaticTargetForModule, the moral equivalent is now:
lookupTarget(Mod->getTargetTriple, true, false, ...);

and pointer width) that getClosestStaticTargetForModule was doing, but this
was deemed unnecessary.

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.
