Chris Lattner c30405e0ee Change ConstantPoolSDNode to actually hold the Constant itself instead of

Chris Lattner 53676dfd33 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).

Chris Lattner a7220851c0 Make several cleanups to Andrews varargs change:
1. Pass Value*'s into lowering methods so that the proper pointers can be
   added to load/stores from the valist
2. Intrinsics that return void should only return a token chain, not a token
   chain/retval pair.
3. Rename LowerVAArgNext -> LowerVAArg, because VANext is long gone.
4. Now that we have Value*'s available in the lowering methods, pass them
   into any load/stores from the valist that are emitted

Andrew Lenharth 39edea8306 Fix 2005-05-12-Int64ToFP
The issue is there is no unsigned -> double conversion, only signed.  So I
need to test the sign and do a different thing depending on it.  Ideally
this should be in a different BB, but in the mean time, I use a branch
free method.

Andrew Lenharth 5e177826fd 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.

Andrew Lenharth 4a73c2cfdc 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.

Chris Lattner 857624f47a Remove support for ZERO_EXTEND_INREG. This pessimizes code, genering stuff
like this:

        ldah $1,1($31)
        lda $1,-1($1)
        and $0,$1,$24

instead of this:

        zap $0,252,$24

To get this back, the selector should recognize the ISD::AND case where this
happens and emit the appropriate ZAP instruction.
