  Log Message:
  -----------
  [SPIR-V] Fix flakiness during switch generation. (#95001)

The case-list of the switches generated by this pass were not
"deterministic" (based on allocation patterns).
This is because the CaseList order relied on an unordered_set order.
Using the sorted exit target list for those should solve the problem.

Fixes #94961
