that shifts and rotates use the type returned
by getShiftAmountTy for the amount. This
exposed some problems in CellSPU and PPC,
which have already been fixed.

- This explicitly models the costs for functions which should
"always" or "never" be inlined. This fixes bugs where such costs
were not previously respected.

so that va_start/va_arg/et.al. will walk arguments correctly for Cell SPU.
N.B.: Because neither clang nor llvm-gcc-4.2 can be built for CellSPU, this is
still unexorcised code.

allows ppcf128->int conversion to work with
DeadInstructionElimination. This is now turned
off but RM is harmless. It does not do a complete
job of modeling the rounding mode.
Revert marking MFCR as using all 7 CR subregisters;
while correct, this caused the problem in PR 2964,
plus the local RA crash noted in the comments.
This was needed to make DeadInstructionElimination,
but as we are not running that, it is backed out
for now. Eventually it should go back in and the
other problems fixed where they're broken.

other day that PPC custom lowering could create
a BUILD_PAIR of two f64 with a result type of...
f64! - already fixed). Fix a place that triggers
the sanity check.

is morphed by AnalyzeNewNode into a previously
processed node, and different result values of
that node are remapped to values with different
nodes, then we could end up using wrong values
here [we were assuming that all results remap
to values with the same underlying node]. This
seems theoretically possible, but I don't have
a testcase. The meat of the patch is in the
changes to AnalyzeNewNode/AnalyzeNewValue and
ReplaceNodeWith. While there, I changed names
like RemapNode to RemapValue, since it really
remaps values. To tell the truth, I would be
much happier if we were only remapping nodes
(it would simplify a bunch of logic, and allow
for some cute speedups) but I haven't yet worked
out how to do that.

Since the ARM constant pool handling supercedes the standard LLVM constant
pool entirely, the JIT emitter does not allocate space for the constants,
nor initialize the memory. The constant pool is considered part of the
instruction stream.
Likewise, when resolving relocations into the constant pool, a hook into
the target back end is used to resolve from the constant ID# to the
address where the constant is stored.
For now, the support in the ARM emitter is limited to 32-bit integer. Future
patches will expand this to the full range of constants necessary.

ppcf128 to i32 conversion and expand it into a code
sequence like in LegalizeDAG. This needs custom
ppc lowering of FP_ROUND_INREG, so turn that on and
make it work with LegalizeTypes. Probably PPC should
simply custom lower the original conversion.

to see waht is about to be selected and what the resulting subgraph
looks like. This really helps when debugging instruction selection.

This prevents the fold/unfold code from pointing to the wrong register.

added a doNotCSE predicate and used it to reduce code
duplication (some of the duplicated code was wrong...).
This fixes ARM/cse-libcalls.ll when using LegalizeTypes.
