5fe575ff4f Eliminate SectionFlags, just embed a SectionKind into Section 
instead and drive things based off of that.

bf36cafb8c fixed incorrect lowering of ISD::SUB node. SUB has only one result value. 
It wasn't caught during tests because we never got a sub generated, (i8 was always getting promoted to int, which in turn was broken into subc/sube). Though the optimizer leaves an i8 sub now.

d83360694a Rename tMOVhi2lor to tMOVgpr2tgpr. It's not moving from a high register to a low register. It's moving from a GPR register class to a more restrictive tGPR class. Also change tMOVlor2hir, and tMOVhir2hir.

0fcf4dc6d3 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.

namespace which could very well conflict with non-LLVM code.

Also clean up some spacing, remove an extra header.

e346e180f3 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.

a5881e3060 Add TargetRegistry::lookupTarget. 
- This is a simplified mechanism which just looks up a target based on the
   target triple, with a few additional flags.

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

 - This no longer does the fuzzy matching with target data (based on endianness
   and pointer width) that getClosestStaticTargetForModule was doing, but this
   was deemed unnecessary.
