ae528f65ba MC/X86: Add custom hack for recognizing "imul $12, %eax" and friends.

ee9102587e MC/X86: Warn on scale factors > 1 without index register, instead of erroring, 
for 'as' compatibility.

a273442891 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.

05ea54e886 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.

1f1b865c40 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.

Intended to help ease reproducing problems by increasing base register usage
after heuristics for only using the when needed are in place.

4ce307f963 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.

b82b4339d1 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
