62547267f0 More binary encoding stuff, taking advantage of the new "by name" operand 
matching in tblgen to do the predicate operand.

40ef4fe82a Properly handle reloading and spilling around partial redefines in 
LocalRewriter.

This is a bit of a hack that adds an implicit use operand to model the
read-modify-write nature of a partial redef. Uses and defs are rewritten in
separate passes, and a single operand would never be processed twice.

60cb528246 Per discussion with Sanjiv, remove the PIC16 target from mainline. When/if 
it comes back, it will be largely a rewrite, so keeping the old codebase
in tree isn't helping anyone.

749dc72bdc fix the expansion of va_arg instruction on PPC to know the arg 
alignment for PPC32/64, avoiding some masking operations.

llvm-gcc expands vaarg inline instead of using the instruction
so it has never hit this.

56ac907c57 Implement a few more binary encoding bits. Still very early stage proof-of- 
concept level stuff at this point, but it is generally working for those
instructions that know how to map the operands.

This patch fills in the register operands for add/sub/or/etc instructions
and adds the conditional execution predicate encoding.
