1264b7cab8 First bit of support for the dwarf .loc directive. This patch updates the 
needed parsing for the .loc directive and saves the current info from that
into the context.  The next patch will take the current loc info after an
instruction is assembled and save that info into a vector for each section for
use to build the line number tables.  The patch after that will encode the info
from those vectors into the output file as the dwarf line tables.

b77d67f318 Move enabling the local stack allocation pass into the target where it belongs. 
For now it's still a command line option, but the interface to the generic
code doesn't need to know that.

a209503467 Use MapValue in the Linker instead of having a private function 
which does the same thing. This eliminates redundant code and
handles MDNodes better. MDNode linking still doesn't fully
work yet though.

3b96ffdac1 MC/Parser: Accept leading dollar signs in identifiers. 
- Implemented by manually splicing the tokens. If this turns out to be
   problematically platform specific, a more elegant solution would be to
   implement some context dependent lexing support.

35b7c033d4 add ARM cmd line option to force always using virtual base regs when possible. 
Intended to help ease reproducing problems by increasing base register usage
after heuristics for only using the when needed are in place.

6901283544 MapValue support for MDNodes. This is similar to r109117, except 
that it avoids a lot of unnecessary cloning by avoiding remapping
MDNode cycles when none of the nodes in the cycle actually need to
be remapped. Also it uses the new temporary MDNode mechanism.

5ee026c512 Check in a couple of changes that I apparently never committed: 
- teach DifferenceEngine to unify successors of calls and invokes
    in certain circumstances
  - basic blocks actually don't have their own numbering;  did that change?
  - add llvm-diff to the Makefile and CMake build systems

eb47692c22 Add register class hack that needs to go away, but makes it more obvious
