cff0f48d34 C++: Work around join-order issue in flow-through 
In this non-linear recursion, a `#prev` relation was joined earlier than
the `#prev_delta` relation. As a result, each iteration of the predicate
processes every tuple from previous iterations.

This quadratic behavior caused severe slowdowns on oneapi-src/oneDNN.

17beb2d867 C++: Remove big-step relation in flow-through code 
This relation was originally introduced to improve performance but may
no longer be necessary. The `localFlowStepPlus` predicate had an
explosion of tuples on oneapi-src/oneDNN for C++.

6de3d5bc3d C++: Change opcode QLDocs to refer to instruction QLDocs 
As discussed in today's C++ analysis team meeting. `Opcode` is rarely used directly, so we'll just refer to the documentation for the corresponding `Instruction` class.

I've preserved the script in case we want to do a bulk change of all of the `Opcode` comments, but I don't expect it will be needed if we just add a new `Opcode` or two.

281985b845 C++: Sync Opcode.qll QLDoc with Instruction.qll QLDoc 
For every concrete `Opcode`, there is a corresponding `Instruction` class. Rather than duplicate all of the QLDoc by hand, I wrote a quick Python script to copy the QLDoc from `Instruction.qll` to `Opcode.qll`. I don't expect that we will need to do this often, so I'm not hooking it up to a PR check or anything like that, but I did commit the script itself in case we need it again.

023e1dc0a2 Instruction and opcode cleanup 
- Renamed `DynamicCastToVoid` to the more descriptive `CompleteObjectAddress`
- Split verbose description from summary in a few Instruction QLDoc comments.
- Added `Instruction` classes for the few remaining `Opcode`s that didn't have one.
- Removed a use of "e.g."
