The TargetRegistry is just a namespace-like class, instantiated in one
place to use a range-based for loop. Instead, expose access to the
registry via a range-based 'targets()' function instead. This makes most
uses a bit awkward/more verbose - but eventually we should just add a
range-based find_if function which will streamline these functions. I'm
happy to mkae them a bit awkward in the interim as encouragement to
improve the algorithms in time.

The cpp backend is not a reasonable fallback for a missing target. It is a
very special backend, so it is reasonable to use it only if explicitly
requested.
While at it, simplify the interface a bit.

This makes using array_pod_sort significantly safer. The implementation relies
on function pointer casting but that should be safe as we're dealing with void*
here.

Get back getHostTriple.
For JIT compilation, use the host triple instead of the default
target: this fixes some JIT testcases that used to fail when the
compiler has been configured as a cross compiler.

The header file was already properly located. The previous need for it
in Support had to do with the version string printing which was fixed in
r135757.
Also update build dependencies where libraries that needed the
functionality of the Target library (in the form of the TargetRegistry)
were picking it up via Support. This is pretty pervasive, essentially
every TargetInfo library (ARMInfo, etc) uses TargetRegistry, making it
depend on Target. All of these were previously just sneaking by.

function on the TargetRegistry. Also clean it up and use the modern LLVM
utility libraries available instead of rolling a few things manually.

- 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.

- 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.

Targets implement a single global Target structure which will live in a new
<Target>/TargetInfo library; this will be present in any image which the target
is usable in.
- Optional target specific classes can then be registered and attached to the
Target description.
- Registration for normal Targets will be done via the initialization functions
instead of using static constructors.
- This allows clients to use a single interface to obtain target data, without
requiring the code generator be linked in. It also provides a natural
extension point for adding new optional target data (assembler parser,
disassembler, etc.).
- This also provides a new entry point for obtaining a target for a particular
triple (without a module).
- Not yet used, however this should eventually replace the TargetMachineRegistry.
