51b81c9930 Provide TargetMachine implementations with reference to Target they were created 
from.
 - This commit is almost entirely propogating the reference through the
   TargetMachine subclasses' constructor calls.

1d5b4e20c9 Migrate llc and the JIT to using the TargetRegistry for lookups. 
- They still use the TargetMachineRegistry to populate the contents of the
   -march option (via the listener interface). We can't just populate it in the
   option parser because we can't expect the TargetRegistry to be populated yet
   (we no longer rely on static constructors).

 - There are a couple ways to finish killing off TargetMachineRegistry, but I
   haven't figured out the cleanest one yet...

f69bd722c3 Allow multiple registrations of the same target. 
- This doesn't necessarily seem like a good idea, but the JIT unittest
   currently relies on it.

61ce410af9 Reimplement TargetMachineRegistry in terms of TargetRegistry. 
- This is a temporary hack to aid in incremental refactoring, for now we
   allocate a new TargetMachineRegistryEntry on every getClosest... call.

 - No intended functionality change, other than the leaked memory.

- This abuses TargetMachineRegistry's constructor for now, this will get
   cleaned up in time.

cc2e2f1506 Add new TargetRegistry. 
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.

499fe29f12 fix an arm codegen bug (the same as PR4482 on ppc) where available_externally 
symbols were not getting stubs.  While I'm at it, add a big testcase for
stub generation to make sure I don't break anything.

with the mangler (like x86 and ppc), instead of going through 
printSuffixedName.

0c13774a29 get the PPC stub temporary label from the mangler instead of 
using horrible string hacking.  This gives us a different label,
but it's just an assembler temporary, so the name doesn't matter.

2f7a01f535 simplify "EmitExternalGlobal": it is only used to output a 
reference to the personality function for a module, and
those are all added to the GVStubs array by looping
over MMI->getPersonalities()
