- Fix a couple of minor bugs in i16immSExt8 and i16immZExt8.
- Added loadiPTR fragment used for indirect jumps and calls.

M_LOOK_UP_PTR_REG_CLASS which allows the register class of the operand to be
resolved via a callback at runtime.

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.

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.

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.
