TODO: Split out reg info stuff
llvm-svn: 567

Move files from lib/CodeGen/TargetMachine to lib/Target
Move TargetData.h and TargetMachine.h to Target/{Data.h|Machine.h}
Prepare to split TargetMachine.h into several smaller files

llvm-svn: 566

1. Clean up the TargetMachine structure.  No more wierd pointers that have to
   be cast around and taken care of by the target.
2. Instruction Scheduling now takes the schedinfo as an argument.  The same
   should be done with the instinfo, it just isn't now.
