Context:
For those passes require to trace the qubit to find the index or extract op, they usually implement the qubit SSA tracking in their pass. This PR is intend to make a helper function for this purpose, people can reuse it instead of inventing their own. Plan to use it in the following PR for supporting
wiregrouping strategy in split-non-commuting pass.Description of the Change:
Introduce a
traceQubitutility (Quantum/Utils/QubitTracing.h) that walks a qubit SSA value backward to thequantum.extractresult that defines the logical wire.Benefits:
Possible Drawbacks:

[sc-109333]EDIT: I just realize I don't need it to finish the split-non-commuting feature. So I just put here if anyone need it.
