[OperandBundles] Allow operand-specific attributes in operand bundles

Currently `OperandBundleUse::operandsHaveAttr` computes its result
without being given a specific operand.  This is problematic because it
forces us to say that, e.g., even non-pointer operands in `"deopt"`
operand bundles are `readonly`, which doesn't make sense.

This commit changes `operandsHaveAttr` to work in the context of a
specific operand, so that we can give the operand attributes that make
sense for the operands's `llvm::Type`.
