Summary:
This hasn't been caught before because it requires noalias or similarly
strong alias analysis to actually reproduce.

Sanjoy Das b7e861a488 Add safety check to InstCombiner::commonIRemTransforms
Since FoldOpIntoPhi speculates the binary operation to potentially each
of the predecessors of the PHI node (pulling it out of arbitrary control
dependence in the process), we can FoldOpIntoPhi only if we know the
operation doesn't have UB.

This also brings up an interesting profitability question -- the way it
is written today, commonIRemTransforms will hoist out work from
dynamically dead code into code that will execute at runtime.  Perhaps
that isn't the best canonicalization?

Fixes PR27968.

Sanjoy Das 4d4339d1e8 [PM] Port IndVarSimplify to the new pass manager
Summary:
There are some rough corners, since the new pass manager doesn't have
(as far as I can tell) LoopSimplify and LCSSA, so I've updated the
tests to run them separately in the old pass manager in the lit tests.
We also don't have an equivalent for AU.setPreservesCFG() in the new
pass manager, so I've left a FIXME.

Chandler Carruth 806faaef8b Disable the use of std::call_once on PowerPC due to an apparent bug in
libstdc++ (or in compilers, or somewhere, I can't track it down) that
causes unittests that use INITIALIZE_PASS to crash.

The analysis I've been able to do is that inside libstdc++'s
implementation of std::call_once, it uses pthread_once, and when that
returns an error code it throws std::system_error which then eventually
calls std::terminate.

Hopefully some of the folks who work on PPC can try to sort out what's
going on here. Until then, they'll have to use the fallback
implementation.

Change the name of the ICmpInst to 'ICmp' and the Constant (was a ConstantInt) to 'C',
so that it's hopefully clearer that 'CI' refers to CastInst in this context.

While we're scrubbing, fix the documentation comment and use 'auto' with 'dyn_cast'.

David Majnemer 2482e1c017 [SimplifyCFG] Don't kill empty cleanuppads with multiple uses
A basic block could contain:
  %cp = cleanuppad []
  cleanupret from %cp unwind to caller

This basic block is empty and is thus a candidate for removal.  However,
there can be other uses of %cp outside of this basic block.  This is
only possible in unreachable blocks.

Make our transform more correct by checking that the pad has a single
user before removing the BB.

This fixes PR28005.
