4a0b108f33 Apparently this is needed for llvm-link to link. 
Untested.

7637f43217 Allow strict subclasses of register classes, this way we can handle 
ARM instructions with:

foo GPR, rGPR

which happens a lot.

e0cdfa265a In the default address space, any GEP off of null results in a trap value if you try to load it. Thus, 
any load in the default address space that completes implies that the base value that it GEP'd from
was not null.

6e1e480f13 Don't include the is-function-local bit in the FoldingSetNodeID 
for MDNodes, since this information is effectively implied by
the operands. This allow allows the code to avoid doing a
recursive is-it-really-function-local check in some cases.

024b04ad93 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.

0c3eb7ca50 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.

30fd721e48 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.

7859dfd71b 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.

5cbd5888e7 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.

4e49cb4a11 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
