Sanjoy Das bcd150362a [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.
