92ad57f066 Move some of the decision logic for converting an instruction into one that sets 
the 'zero' bit down into the back-end. There are other cases where this logic
isn't sufficient, so they should be handled separately.

220e240bdf Modify the comparison optimizations in the peephole optimizer to update the 
iterator when an optimization took place. This allows us to do more insane
things with the code than just remove an instruction or two.

efe7d9a12f Fix merging base-updates for VLDM/VSTM: Before I switched these instructions 
to use AddrMode4, there was a count of the registers stored in one of the
operands.  I changed that to just count the operands but forgot to adjust for
the size of D registers.  This was noticed by Evan as a performance problem
but it is a potential correctness bug as well, since it is possible that this
could merge a base update with a non-matching immediate.

3ef1c8759a Teach if-converter to be more careful with predicating instructions that would 
take multiple cycles to decode.
For the current if-converter clients (actually only ARM), the instructions that
are predicated on false are not nops. They would still take machine cycles to
decode. Micro-coded instructions such as LDM / STM can potentially take multiple
cycles to decode. If-converter should take treat them as non-micro-coded
simple instructions.

5f54ce3473 For each instruction itinerary class, specify the number of micro-ops each 
instruction in the class would be decoded to. Or zero if the number of
uOPs must be determined dynamically.

This will be used to determine the cost-effectiveness of predicating a
micro-coded instruction.
