cac7b248c7 Make sure that the call stack adjustments have default operands. Also 
leave custom lowerings for later.

Fixes some nightly tests.

a0a5015a35 PowerPC varargs functions store live-in registers on the stack. Make sure we use 
virtual registers for those stores since RegAllocFast requires that each live
physreg only be used once.

This fixes PR8357.

Also don't use fast-isel on non-darwin since it's untested.

ecf3e62010 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.

c9709f154d 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.

2b428a0ab8 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.

15fc769cf2 Correct some load / store instruction itinerary mistakes: 
1. Cortex-A8 load / store multiplies can only issue on ALU0.

3. Correctly model all vld1 and vld2 variants.

c425302670 Do not check that the bodies of two defs of same linkonce global are the same.

3075d28c15 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.

d64a33ade4 Filter out illegal formulae after updating offsets, not before, so that 
formulae which become illegal as a result of the offset updating don't
escape.
