Chris Lattner 74f60c306d Refactor to use Target.getRegisterClasses consistently, which provides 
anonymous regclass definition renaming.

Change the generated code to emit register classes as properly namespace
qualified entities like everything else.

expose the actual class definition as an object, though this isn't quite
usable yet.

specify aliases directly in register definitions.

Reid Spencer 7c16caa336 Changes For Bug 352 
Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.

Alkis Evlogimenos 5f1f337d95 Change MRegisterDesc::AliasSet, TargetInstrDescriptor::ImplicitDefs 
and TargetInstrDescriptor::ImplicitUses to always point to a null
terminated array and never be null. So there is no need to check for
pointer validity when iterating over those sets. Code that looked
like:

if (const unsigned* AS = TID.ImplicitDefs) {
  for (int i = 0; AS[i]; ++i) {
    // use AS[i]
  }
}

was changed to:

for (const unsigned* AS = TID.ImplicitDefs; *AS; ++AS) {
  // use *AS
}
