82482944ed TargetAsmInfo::getAddressSize() was incorrect for x86-64 and 64-bit targets 
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.

fc3282221f CollectorMetadata abstractly describes stack maps for a function. 
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.

42d60274ea - Move getPhysicalRegisterRegClass() from ScheduleDAG to MRegisterInfo. 
- Added ability to emit cross class register copies to the BBRU scheduler.
- More aggressive backtracking.

a6fb1b6743 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.

to prevent surprising match when called with const
argument.

of exception handling emission -- so there's no need to cache it.

it appears, and do something reasonable with x86

to/from int, mostly).
