346dc6fed1 Use getExtLoad here instead of getNode, as extloads produce two values. This 
fixes a legalize failure on SPASS for itanium.

3aa7a188b9 Now that we have int/fp lattice values, implement the SDTCisOpSmallerThanOp 
type constraint.  This lets tblgen realize that it doesn't need any dynamic
type checks for fextend/fround on PPC (and many other targets), because there
are only two fp types.

28621890d9 Fairly serious rework of the typing code to add new int/fp lattice values. 
Overall, no functionality change yet though.

81047cdfc0 Implement a couple of new (important) features. 
1. If an operation has to be int or fp and the target only supports one
   int or fp type, relize that the op has to have that type.
2. If a target has operations on multiple types, do not emit matching code
   for patterns involving those operators, since we do not emit the code to
   check for them yet.  This prevents PPC from generating FP ops currently.

Also move some code around into more logical places.

c206a2a32a Relax the checking on zextload generation a bit, since as sabre pointed out 
you could be AND'ing with the result of a shift that shifts out all the
bits you care about, in addition to a constant.

Also, move over an add/sub_parts fold from legalize to the dag combiner,
where it works for things other than constants.  Woot!

b1d64c386b Fix a potential bug with two combine-to's back to back that chris pointed 
out, where after the first CombineTo() call, the node the second CombineTo
wishes to replace may no longer exist.

Fix a very real bug with the truncated load optimization on little endian
targets, which do not need a byte offset added to the load.

d97bb9d084 More cool stuff for the dag combiner. We can now finally handle things 
like turning:

_foo:
        fctiwz f0, f1
        stfd f0, -8(r1)
        lwz r2, -4(r1)
        rlwinm r3, r2, 0, 16, 31
        blr

into
_foo:
        fctiwz f0,f1
        stfd f0,-8(r1)
        lhz r3,-2(r1)
        blr

Also removed an unncessary constraint from sra -> srl conversion, which
should take care of hte only reason we would ever need to handle sra in
MaskedValueIsZero, AFAIK.
