other than PPC64. Instead of fixing it, just remove it and fix all the
places that use it to use TargetData::getPointerSize() instead, as there
aren't very many. Most of the references were in DwarfWriter.cpp.

It includes:

 - location and of each safe point in machine code (identified by a
   label)
 - location of each root within the stack frame (identified by an
   offset), including the metadata tag provided to llvm.gcroot in
   the user program
 - size of the stack frame (for collectors which want to cheat on
   stack crawling :)
 - and eventually will include liveness

It is to be populated by back-ends during code-generation.

CollectorModuleMetadata aggregates this information across the
entire module.

Added major new capabilities to scheduler (only BURR for now) to support physical register dependency. The BURR scheduler can now backtrace and duplicate instructions in order to avoid "expensive / impossible to copy" values (e.g. status flag EFLAGS for x86) from being clobbered.
