89a0d10812 Upgrade some load/store instructions to use the proper addressing mode stuff.

81845946ff fix some assumptions that pointers can only be 32-bits. With this, we can 
now compile:

static unsigned long X;
void test1() {
  X = 0;
}

into:

_test1:
        lis r2, ha16(_X)
        li r3, 0
        stw r3, lo16(_X)(r2)
        blr

Totally amazing :)

6a9ec7e80e Don't pass target name into TargetData anymore, it is never used or needed. 
Remove explicit casts to std::string now that there is no overload resolution
issues in the TargetData ctors.

19680a4928 Document the subtarget features better, make sure that 64-bit mode, 64-bit 
support, and 64-bit register use are all consistent with each other.

Add a new "IsPPC" feature, to distinguish ppc32 vs ppc64 targets, use this
to configure TargetData differently.  This not makes ppc64 blow up on lots
of stuff :)

fa884ac11b Rename some subtarget features. A CPU now can *have* 64-bit instructions, 
can in 32-bit mode we can choose to optionally *use* 64-bit registers.

that is currently just like ppc32 :)

6f45959365 Gaar! Don't use r11 for CR save/restore, use R0. R11 can be register 
allocated, thus live across the save/reload.  This fixes

b231c3d11c Fix a problem exposed by the local allocator. CALL instructions are not marked 
as using incoming argument registers, so the local allocator would clobber them
between their set and use.  To fix this, we give the call instructions a variable
number of uses in the CALL MachineInstr itself, so live variables understands
the live ranges of these register arguments.

03c70b7f27 Switch PPC over to a call-selection model where the lowering code creates 
the copyto/fromregs instead of making the PPCISD::CALL selection code create
them.  This vastly simplifies the selection code, and moves the ABI handling
parts into one place.

348883611c 3 changes, 2 of which are cleanup one of which changes codegen: 
1. Rearrange code a bit so that the special case doesn't require indenting lots
   of code.
2. Add comments describing PPC calling convention.
3. Only round up to 56-bytes of stack space for an outgoing call if the callee
   is varargs.  This saves a bit of stack space.

b5271a0f4c Instead of implementing LowerCallTo directly, let the default impl produce an 
ISD::CALL node, then custom lower that.  This means that we only have to handle
LEGAL call operands/results, not every possible type.  This allows us to
simplify the call code, shrinking it by about 1/3.

0a12e343e2 Switch the PPC backend over to using FORMAL_ARGUMENTS for formal argument 
handling.  This makes the lower argument code significantly simpler (we
only need to handle legal argument types).

Incidentally, this also implements support for vector argument registers,
so long as they are not on the stack.
