[OperandBundles] Treat "deopt" operand bundles specially

Teach LLVM optimize to more precisely in the presence of "deopt" operand
bundles.  "deopt" operand bundles imply that the call they're attached
to is at least `readonly` (i.e. they don't imply clobber semantics), and
they don't capture their bundle operands.

[OperandBundles] Teach AliasAnalysis about operand bundles

Summary:
If a `CallSite` has operand bundles, then do not peek into the called
function to get a more precise `ModRef` answer.

This is tested using `argmemonly`, `-basicaa` and `-gvn`; but the
functionality is not specific to any of these.

Depends on D13961
