Support single-fp incoming args.

2a9f539168 Fix bug in copying long constants to register pairs. We were getting
the top and bottom halves backwards...how embarrassing.
Support 'cast long to long' and other similar no-op casts to long.
Support 'ret long'.

ec3227fe39 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.

c7fd0f4675 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.

4473303453 Rename the load and store opcodes. The non-fp ones only have one
variant worth worrying about; the fp ones have two.
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.
Support load and store of float and double.

7548a540f7 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.

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.

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)

Implement some simple casts: integral, smaller than longs, and equal-width
 or narrowing only.

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.

2d4fa8faac Preliminary support for getting 64-bit integer constants into registers.
Preliminary support for division. It's gross because you have to initialize
the "Y" register, which is the top 32 bits of the thing you're dividing.
