Revert "Optimize DefUseManager allocations (#4709)" (#4846)

This reverts commit d18d0d92e55f44da6af0dc87fb0e3c8034e9a3ac.

This is reverted because it causes a 7X slowdown when legalizing
SPIR-V with NonSemantic.Shader.DebugInfo.100 instructions.
This is due to the creation of very large UseLists for several
heavily used operands for this extension combined with the fact
that the original commit changed the performance of Uselists to O(n).
