0cee4d2fb9 Trim whitespace. 
Support cast of ints (and narrower) to float and double.
Support cast double to double (using load and store).
Abort if we see a CallInst or SetCondInst with long/fp args, instead
of producing bad code.
Support add, sub, mul, div of float and double.

da38dc5180 Made a fix so that you can print out MachineInstrs that belong to a MachineBasicBlock that is not yet attached to a MachineFunction. This change includes changing the third operand (TargetMachine) to a pointer for the MachineInstr::print function.

ec698da314 In emitting code for a GEP instr, iterate over GEPTypes because there is one

9a7eca6c51 Use correct add*Imm form in more BuildMI calls. 
Fix bug in emitGEPOperation where we weren't passing MBB, IP to getReg.
(hey, wouldn't a constant expression lowering pass be cool? huh huhuhuh)
Fix bug in emitGEPOperation where we might try to OR a constant into a
register which was too big to fit in the immediate field.
Support and, or, xor of longs.

e39ef4e8b9 Rename the load and store opcodes. The non-fp ones only have one

Stub out the case analysis of int-to-fp casts (no code yet).
I think the number of operands passed to BuildMI for loads was wrong.

236ef1542c Strange as it may sound, we'll not use LDD/STD to store longs. For reasons of 
representational consistency, we want to address the halves of each 64-bit value
separately.
