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.

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.

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.

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.
