add more such code for DIEDwarfLabel::SizeOf and DIEObjectLabel::SizeOf.

068317bfa3 Refactor the memcpy lowering for the x86 target.
The only generated code difference is that now we call memcpy when
the size of the array is unknown. This matches GCC behavior and is
better since the run time value can be arbitrarily large.

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.

ff11026575 - Added MRegisterInfo::getCrossCopyRegClass() hook. For register classes where reg to reg copies are not possible, this returns another register class which registers in the specified register class can be copied to (and copy back from).
- X86 copyRegToReg() now supports copying between EFLAGS and GR32 / GR64 registers.

48d1e4517e When mixing SSE and x87 codegen, it's possible to
have situations where an SSE instruction turns into
multiple blocks, with the live range of an x87
register crossing them.  To do this correctly make
sure we examine all blocks when inserting
FP_REG_KILL.  PR 1697.  (This was exposed by my
fix for PR 1681, but the same thing could happen
mixing x87 long double with SSE.)

9b4baf1692 claim that "st" is from the 80-bit register file. This causes x87-using inline
asm to die with:

ScheduleDAG.cpp:269: failed assertion `false && "Couldn't find the register class"'

instead of:
failed assertion `RegMap->getRegClass(VReg) == RC && "Register class of operand and regclass of use don't agree!"'

yay.

d20c824b20 Factor the dominator tree calculation details out into DominatorCalculation.h. This
change is not useful in and of itself, but it lays the groundwork for combining
the dominator and postdominator implementations.

Also, factor a few methods that are common to DominatorTree and PostDominatorTree
into DominatorTreeBase.  Again, this will make merging the two calculation methods
simpler in the future.
