Nate Begeman 1b8121b227 Add bswap, rotl, and rotr nodes 
Add dag combiner code to recognize rotl, rotr
Add ppc code to match rotl

Targets should add rotl/rotr patterns if they have them

Evan Cheng 9ae486047e * Removed the use of FLAG. Now use hasFlagIn and hasFlagOut instead. 
* Added a pseudo instruction (for each target) that represent "return void".
  This is a workaround for lack of optional flag operand (return void is not
  lowered so it does not have a flag operand.)

Nate Begeman 53c1f75090 Since extload can also be used by FP, split STDIntExtLoad into two parts, 
one for use with extload, one for use with sextload and zextload, which
are integer only.

Chris Lattner 27656ac89c Add SDTCisPtrTy and use it for loads, to indicate that the operand of a load 
must be a pointer.  This removes a type check out of the code generated by
tblgen for load matching.

Chris Lattner 282c2af4d8 On some targets (e.g. X86), shift amounts are not the same as the value 
being shifted.  Don't assume they are.

Chris Lattner ce9580fce4 Add nodes for CondCodeSDNode and setcc, and add a bunch of pattern fragments 
to make it easy to use them.  This lets you write patterns like:

(set PRRC:$rd, (setne GPRC:$rS, imm:$SH))

and stuff.
