ca0ef6fe4f [SparcV9]: Use SRL instead of SLL to clear top 32-bits in ctpop:i32. SLL does not clear top 32 bit, only SRL does.

782b70f4b3 Fix aranges and split dwarf by ensuring that the symbol and relocation
back to the compile unit from the aranges section is to the skeleton

Do this by adding a method to grab a forwarded on local sym and local
section by querying the skeleton if one exists and using that. Add
a few tests to verify the relocations are back to the correct section.

For AArch64 backend, if DAGCombiner see "sext(setcc)", it will
combine them together to a single setcc with extended value type.
Then if it see "zext(setcc)", it assumes setcc is Vxi1, and try to

DAGcombiner will create wrong node and get wrong code emitted.

b7d621a6e0 ARM IAS: handle errors more appropriately
Directive parsers must return false if the target assembler is interested in
handling the directive.  The Error member function returns true always.  Using
the 'return Error()' pattern would incorrectly indicate to the general parser
that the target was not interested in the directive, when in reality it simply
encountered a badly formed directive or some other error.  This corrects the
behaviour to ensure that the parser behaves appropriately.

6c9712fecb New machine model for cortex-a9. Schedule for resources and latency.
Schedule more conservatively to account for stalls on floating point

since it's shared between FP and LD/ST instructions. This might not be
completely accurate but should work well in practice.

9eac3a79d9 The Cortex-A9 machine model is incomplete. Mark it as such.
Many vector operations never had itineraries. Since the new machine
model was a mapping from existing itinerary classes, we don't have a
model for these. We still want to migrate A9 even though no one has
invested in a complete model, so mark it incomplete to avoid the
scheduler asserting.

9e76e1d785 Add a PostMachineScheduler pass with generic implementation.
PostGenericScheduler uses either the new machine model or the hazard
checker for top-down scheduling. Most of the infrastructure for PreRA
machine scheduling is reused.

With a some tuning, this should allow MachineScheduler to be default
for all ARM targets, including cortex-A9, using the new machine
model. Likewise, with additional tuning, it should be able to replace
PostRAScheduler for all targets.

The PostMachineScheduler pass does not currently run the
AntiDepBreaker. There is less need for it on targets that are already
running preRA MachineScheduler. I want to prove it's necessary before
committing to the maintenance burden.

The PostMachineScheduler also currently removes kill flags and adds
them all back later. This is a bit ridiculous. I'd prefer passes to
directly use a liveness utility than rely on flags.

A test case that enables this scheduler will be included in a
subsequent checkin that updates the A9 model.
