b1d26f6665 Implement the getPointerRegClass method, which is required for the ptr_rc
magic to work.

4083960147 Move isLoadFrom/StoreToStackSlot from MRegisterInfo to TargetInstrInfo,a far more logical place. Other methods should also be moved if anyoneis interested. :)

1d9d7427c4 First bits of 64 bit PowerPC stuff, currently disabled. A lot of this is
purely mechanical.

redundant after the change.

eb5d47d99d Fix a CQ regression from my patch to split F32/F64 into seperate register
classes on PPC.  We were emitting fmr instructions to do fp extensions, which
weren't getting coallesced.  This fixes Regression/CodeGen/PowerPC/fpcopy.ll

919c032fa4 Modify the ppc backend to use two register classes for FP: F8RC and F4RC.
These are used to represent float and double values, and the two regclasses
contain the same physical registers.

043870dd85 Teach the code generator that rlwimi is commutable if the rotate amount
is zero.  This lets the register allocator elide some copies in some cases.

This implements CodeGen/PowerPC/rlwimi-commute.ll

cb90de37a7 Add ori reg, reg, 0 as a move instruction. This can be generated from
loading a 32bit constant into a register whose low halfword is all zeroes.

We now omit the ori after the lis for the following C code:

int bar(int y) { return y * 0x00F0000; }

_bar:
.LBB_bar_0:     ; entry
        ; IMPLICIT_DEF
        lis r2, 15
        mullw r3, r3, r2
        blr
