cf40e00d32 Make the checks for DW_FORM_data4 consistent with the others, and 
add more such code for DIEDwarfLabel::SizeOf and DIEObjectLabel::SizeOf.

8e1513ad66 Use 32-bit data directives for DW_FORM_data4 format data, even on 
targets with 64-bit addresses.

01b306e575 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.

50747737a5 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.

b20ff7f981 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.

351222b471 GarbageCollection.html is expanded to encompass the coming

0f9e307353 - 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.

Also eliminated allocas from the Ocaml bindings for portability,
