Revert 75762, 75763, 75766..75769, 75772..75775, 75778, 75780, 75782 to repair broken LLVM-GCC build.
Will revert 75770 in the llvm-gcc trunk.

 - Which was already present in the module!

 - I skipped this xform for Alpha, since it runs an extra pass during assembly
   emission, but not when emitting assembly via the DumpAsm flag.

 - No functionality change.

 - This commit is almost entirely propogating the reference through the
   TargetMachine subclasses' constructor calls.

 - 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...

llvm-svn: 75772

 - This doesn't necessarily seem like a good idea, but the JIT unittest
   currently relies on it.

llvm-svn: 75769

llvm-svn: 75767

 - 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.

llvm-svn: 75766

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

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.

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.

but it's just an assembler temporary, so the name doesn't matter.
