b63869a25b fix the default va_arg expansion (in the realignment case) to not implicitly 
truncate the stack pointer to 32-bits on a 64-bit machine.

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.

e9771f15f7 Now using a variant of the existing inlining heuristics to decide whether to create a given specialization of a function in PartialSpecialization. If the total performance bonus across all callsites passing the same constant exceeds the specialization cost, we create the specialization.

15fc769cf2 Correct some load / store instruction itinerary mistakes: 
1. Cortex-A8 load / store multiplies can only issue on ALU0.
2. Eliminate A8_Issue, A8_LSPipe will correctly limit the load / store issues.
3. Correctly model all vld1 and vld2 variants.

68ff81a2e6 add jit support for the new psuedo instructions I added for 
the add/or xform.  The JIT isn't mcized yet, boo.

This fixes Olden/voronoi, bh and a ton of other stuff that
uses the jit.

functions: computeRemainder and rewrite.

When the remainder breaks up into multiple components, remember to rewrite those
uses as well.

c425302670 Do not check that the bodies of two defs of same linkonce global are the same. 
Such a check does not make any sense in presense of inlining and other compiler-dependent stuff.
This should fix bunch of warnings on mingw32.

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.

This is for rdar://8529692. No testcase yet, because the given cases
hit use-list ordering differences.

b6cde7cdf4 Fix operand latency computation in cases where the definition operand is 
implicit. e.g.
%D6<def>, %D7<def> = VLD1q16 %R2<kill>, 0, ..., %Q3<imp-def>                                                                                                                                                                              
%Q1<def> = VMULv8i16 %Q1<kill>, %Q3<kill>, ...

The real definition indices are 0,1.
