23d171a9ed Add floating-point branches and compares. Compares don't complete 
until the next cycle, and there's no interlock, so they effectively
have a delay slot.

0cee4d2fb9 Trim whitespace. 
Support cast of ints (and narrower) to float and double.
Support cast double to double (using load and store).

9a7eca6c51 Use correct add*Imm form in more BuildMI calls. 
Fix bug in emitGEPOperation where we weren't passing MBB, IP to getReg.

Fix bug in emitGEPOperation where we might try to OR a constant into a

236ef1542c Strange as it may sound, we'll not use LDD/STD to store longs. For reasons of

d084a534a2 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.

7cc5d0f106 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
     \      /
