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.

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.
