9c0ab71f4a kill ADD_PARTS & SUB_PARTS and replace them with fancy new ADDC, ADDE, SUBC 
and SUBE nodes that actually expose what's going on and allow for
significant simplifications in the targets.

5f0a3df176 Targets all now request ConstantFP to be legalized into TargetConstantFP.

cff96008ac 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

d87688fe72 * 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.)

c14ad3dec7 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.

ee29c75c65 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.

  chains.

* Added several new SDTypeProfiles for BR, BRCOND, RET, and WRITEPORT.

91450212d4 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.
