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.

1. Cortex-A8 load / store multiplies can only issue on ALU0.
2. Eliminate A8_Issue, A8_LSPipe will correctly limit the load / store issues.

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.

d7b8d91d4a Small patch to restore home register stack space allocation for the Win64 case. Add test case. This code eventually needs to be tighter, since it's always allocating it, even in leaf routines.

7d24705f65 Change register allocation order for ARM VFP and NEON registers to put the 
callee-saved registers at the end of the lists.  Also prefer to avoid using
the low registers that are in register subclasses required by certain
instructions, so that those registers will more likely be available when needed.
This change makes a huge improvement in spilling in some cases.  Thanks to
Jakob for helping me realize the problem.

Most of this patch is fixing the testsuite.  There are quite a few places
where we're checking for specific registers.  I changed those to wildcards
in places where that doesn't weaken the tests.  The spill-q.ll and
thumb2-spill-q.ll tests stopped spilling with this change, so I added a bunch
of live values to force spills on those tests.

cd3167b281 reimplement the second half of the or/add optimization. We should now 
only end up emitting LEA instead of OR.  If we aren't able to promote
something into an LEA, we should never be emitting it as an ADD.

Add some testcases that we emit "or" in cases where we used to produce
an "add".

a0792de66c - Add TargetInstrInfo::getOperandLatency() to compute operand latencies. This 
allow target to correctly compute latency for cases where static scheduling
  itineraries isn't sufficient. e.g. variable_ops instructions such as
  ARM::ldm.
  This also allows target without scheduling itineraries to compute operand
  latencies. e.g. X86 can return (approximated) latencies for high latency
  instructions such as division.
- Compute operand latencies for those defined by load multiple instructions,
  e.g. ldm and those used by store multiple instructions, e.g. stm.

46f55527d8 Generalize tblgen's dag parsing logic to handle arbitrary expressions 
as the operator of the dag.  Specifically, this allows parsing things
like (F.x 4) in addition to just (a 4).

Unfortunately, this runs afoul of an idiom being used by llvmc.  It
is using dags like (foo [1,2,3]) to represent a list of stuff being
passed into foo.  With this change, this is parsed as a [1,2,3] 
subscript on foo instead of being the first argument to the dag.
Cope with this in the short term by requiring a "-llvmc-temp-hack"
argument to tblgen to get the old parsing behavior.
