- 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.

immediately on every output error. Instead, add a flag to
raw_ostream, and set the flag whenever an error is detected.
The flag can be queried and cleared from the public API. This
gives applications more flexibility to handling errors in
application-specific ways.
If the flag is not cleared when the raw_ostream is destructed,
llvm_report_error is called from the destructor. This ensures
that errors are not implicitly silenced, and provides
convenient default behavior for tools like llc and opt.
Clients wishing to avoid llvm_report_error calls from
raw_ostream should check for errors and clear the error flag.

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.
