15b3d2039f 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.

d699ffc2ac Simplify JIT target selection. 
- Instead of requiring targets to define a JIT quality match function, we just
   have them specify if they support a JIT.

 - Target selection for the JIT just gets the host triple and looks for the best
   target which matches the triple and has a JIT.

251177c96e Initial update to VMCore to use Twines for string arguments. 
- The only meat here is in Value.{h,cpp} the rest is essential 'const
   std::string &' -> 'const Twine &'.

a823846bd1 Instead of eagerly creating new SCEVs to replace all SCEVs that are 
affected after a PHI node has been analyzed, just remove affected
SCEVs from the Scalars map, so that they'll be (lazily) recreated as
needed. This avoids creating SCEV objects that aren't actually needed.

Also, rewrite the associated def-use walking code to be non-recursive
and to continue traversing past Instructions that don't have an
entry in the Scalars map.

da42799098 Add a missing ilist_node.h #include to SparseBitVector, and add a very short 
test for it. The test is by no means complete, but it tests the problem I was
fixing.

555ef2f462 MemoryObject - Abstract base class for contiguous addressable memory. 
Necessary for cases in which the memory is in another process, in a
  file, or on a remote machine.

The primary use for this is the llvm-mc disassemblers, so that they
can be targeted at arbitrary objects, not just in-process memory.

3d63455016 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.

4bb9a9a7d3 Replace UniqueSectionForGlobal with getSectionPrefixForUniqueGlobal. 
The later doesn't depend on any crazy LLVM IR stuff, and this
pulls the concatenation of prefix with GV name (the root problem behind
PR4584) out one level.
