should have no state that is specific to particular globals in the
section. In this case, it means the removal of the "isWeak" and
"ExplicitSection" bits. MCSection uses the new form of SectionKind.
To handle isWeak, I introduced a new SectionInfo class, which is
SectionKind + isWeak, and it is used by the part of the code generator
that does classification of a specific global.
The ExplicitSection disappears. It is moved onto MCSection as a new
"IsDirective" bit. Since the Name of a section is either a section
or directive, it makes sense to keep this bit in MCSection. Ultimately
the creator of MCSection should canonicalize (e.g.) .text to whatever
the actual section is.

thing is #if0'd out anyway. Just simplify the code by reducing the interface.
Not deleting this is essential for Bill's continuing happiness.

indicate that it is a predicate, not an emitter. This eliminates TAI
dependencies on Mangler and GlobalValue.

and convert code to using it, instead of having lots of things
poke the isLookupPtrRegClass() method directly.
2. Make PointerLikeRegClass contain a 'kind' int, and store it in
the existing regclass field of TargetOperandInfo when the
isLookupPtrRegClass() predicate is set. Make getRegClass pass
this into TargetRegisterInfo::getPointerRegClass(), allowing
targets to have multiple ptr_rc things.

it is highly specific to the object file that will be generated in the end,
this introduces a new TargetLoweringObjectFile interface that is implemented
for each of ELF/MachO/COFF/Alpha/PIC16 and XCore.
Though still is still a brutal and ugly refactoring, this is a major step
towards goodness.
This patch also:
1. fixes a bunch of dangling pointer problems in the PIC16 backend.
2. disables the TargetLowering copy ctor which PIC16 was accidentally using.
3. gets us closer to xcore having its own crazy target section flags and
pic16 not having to shadow sections with its own objects.
4. fixes wierdness where ELF targets would set CStringSection but not
CStringSection_. Factor the code better.
5. fixes some bugs in string lowering on ELF targets.

'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.

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
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.

for now. Make the section switching directives more consistent
by not including \n and including \t for them all.

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.

- 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.
