fixme from the PowerPC backend. Emit slightly better code for legalizing
select_cc.

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

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.

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.

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.
