6c43f35d74 Fixed a LowerCallTo and LowerArguments bug. They were introducing illegal 
VBIT_VECTOR nodes. There were some confusion about the semantics of
getPackedTypeBreakdown(). e.g. for <4 x f32> it returns 1 and v4f32, not 4,
and f32.

c5d7d7c715 When we legalize target nodes, do not use getNode to create a new node, 
use UpdateNodeOperands to just update the operands!  This is important because
getNode will allocate a new node if the node returns a flag and this breaks
assumptions in the legalizer that you can legalize some things multiple times
and get exactly the same results.

This latent bug was exposed by my ppc patch last night, and this fixes
gsm/toast.

9a2a497284 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.

c8b682ca19 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.

abde460d4f 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.

8ab5fe574a 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.

966454129d Move function-live-in-handling code from the sdisel code to the scheduler. 
This code should be emitted after legalize, so it can't be in sdisel.

Note that the EmitFunctionEntryCode hook should be updated to operate on the
DAG.  The X86 backend is the only one currently using this hook.
