ffaf40a143 Change *EXTLOAD to use an VTSDNode operand instead of being an MVTSDNode. 
This is the last MVTSDNode.

This allows us to eliminate a bunch of special case code for handling
MVTSDNodes.

Also, remove some uses of dyn_cast that should really be cast (which is
cheaper in a release build).

4fd2bde906 If we support structs as va_list, we must pass pointers to them to va_copy 
See last commit for LangRef, this implements it on all targets.

8b64bd0fd5 Implement count leading zeros (ctlz), count trailing zeros (cttz), and count 
population (ctpop).  Generic lowering is implemented, however only promotion
is implemented for SelectionDAG at the moment.

More coming soon.

2a00530fa7 Implement Value* tracking for loads and stores in the selection DAG. This enables one to use alias analysis in the backends. 
(TRUNK)Stores and (EXT|ZEXT|SEXT)Loads have an extra SDOperand which is a SrcValueSDNode which contains the Value*.  Note that if the operation is introduced by the backend, it will still have the operand, but the value* will be null.

26c7c9150a Elimate handling of ZERO_EXTEND_INREG. This causes the PPC backend to emit 
andi instructions instead of rlwinm instructions for zero extend, but they
seem like they would take the same time.

99fb6814bd 64b: Expand S/UREM 
32b: No longer pattern match fneg(fsub(fmul)) as fnmsub
     Pattern match fsub a, mul(b, c) as fnmsub
     Pattern match fadd a, mul(b, c) as fmadd
Those changes speed up hydro2d by 2.5%, distray by 6%, and scimark by 8%
