untangle a TargetAsmInfo hack where ELFTargetAsmInfo would create a
...
'unnamed' bss section, but some impls would want a named one. Since
they don't have consistent behavior, just make each target do their
own thing, instead of doing something "sortof common" then having
targets change immutable objects later.

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.

Enable EH on PPC Darwin. This basically works; there

are a couple of issues that show up with the optimizer,
but I don't think they're really EH problems.
(llvm-gcc testsuite users note: By default the testsuite
uses the unwinding code that's built as part of your local
llvm-gcc, which does not work. You need to trick it into
using the installed system unwinding code to get useful
results.)
