4f217fdd10 Mess around with allocation order. In particular, I think we ought to be 
using the local & in regs first because they are not clobbered by calls.

6c868a4c17 Support generating machine instructions for Phi nodes (based on x86, but with 
modifications for 1 LLVM BB --> many MBBs).
Fix store operand order: make it always be Base, Offset, SrcReg (think
"[ Base + Offset ] = SrcReg").
Rewrite visitBranchInst() to be even dumber (but working) -- give up on
the branch fallthrough trick, for the time being.
Make visitSetCondInst() work.

09c1309814 Use addGlobalAddress and addMBB for call & branch targets instead of addPCDisp. 
Abort if we see a PCRelativeDisp MachineOperand, to be safe. This matches
the X86 backend.

429022bf83 Add support for widening integral casts. 
Flesh out the SetCC support... which currently ends in a little bit
of unfinished code (which is probably completely hilarious) for
generating the condition value splitting the basic block up into 4
blocks, like this (clearly a better API is needed for this!):

       BB
   cond. branch
     /         /          R1=1    R2=0
     \      /
      \    /
    R=phi(R1,R2)

d54c38b2f4 It's setting up the call args right now, but on the callee side, it's 
trying to get incoming args off the stack, instead of the %i0...%i6 regs,
which is wrong.

4d0cda4d5c This is a start on handling setcc instructions. As the comment notes, we 
have no good way of handling this until the code generator is improved.
We should probably just emit V9 instructions in the meantime.
