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.

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.
