4185d03dc5 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.

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'.

8a0ae9e9ca Support printing constant pool indices.

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.

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.

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.

Rewrite visitBranchInst() to be even dumber (but working) -- give up on
the branch fallthrough trick, for the time being.
Make visitSetCondInst() work.
