cd8f92bc62 Cleanup the JIT as per PR176. This renames the VM class to JIT, and merges the 
VM.cpp and JIT.cpp files into JIT.cpp.  This also splits some nasty code out
into TargetSelect.cpp so that people hopefully won't notice it.  :)

90aeecae42 Add TwoAddressInstructionPass to handle instructions that have two or 
more operands and the two first operands are constrained to be the
same. The pass takes an instruction of the form:

        a = b op c

and transforms it into:

        a = b
        a = a op c

and also preserves live variables.

382bfbffeb When a variable is killed and redifined in a basic block only one 
killing instruction is tracked. This causes the LiveIntervals to
create bogus intervals. The workaound is to add a range to the
interval from the redefinition to the end of the basic block.

457dd0b6c7 Add a new AliassetTracker::remove method. Because we need to be able to remove 
a pointer from an AliasSet, maintain the pointer values on a doubly linked
list instead of a singly linked list, to permit efficient removal from the
middle of the list.

fe533cc4e6 Reorganized the Sparc backend to be more modular -- each different 
implementation of a Target{RegInfo, InstrInfo, Machine, etc} now has a separate
header and a separate implementation file.

This means that instead of a massive SparcInternals.h that forces a
recompilation of the whole target whenever a minor detail is changed, you should
only recompile a few files.

Note that SparcInternals.h is still around; its contents should be minimized.

65ab1b90ee Since we are now in the 'llvm' namespace, the mangled C++ name of structs 
and hence the links, all change.
