ec4b73cb09 Nuke the PowerPCTargetMachine.h header. Note that the PowerPCTargetMachine
still should be merged into the PPC32TargetMachine class

e0de44adba Remove an unnecsesary file. PPC32 and PPC64 share architected registers.
We will decide with subtarget support whether we ever use an i64 register
class.

603d78c9de 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.

0ee7cff4fb 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.

5054f16212 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!

3df4d525c5 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.
