[IR] Add operand bundles to CallInst and InvokeInst.
Summary:
This change teaches `CallInst`s and `InvokeInst`s to maintain a set of
operand bundles as part of its operands. `CallInst`s and `InvokeInst`s
with operand bundles co-allocate some space before their `Use` array to
hold meta information about which of its operands are part of an operand
bundle.
The strings corresponding to the bundle tags are interned into
`LLVMContextImpl::BundleTagCache`
This change does not include any parsing / bitcode support. That's the
next change.
Depends on D12455.
