[Mlir-commits] [mlir] [MLIR] Fix pipelineInitializationKey never being correctly updated (PR #150948)

[Will Froom]

https://github.com/WillFroom created https://github.com/llvm/llvm-project/pull/150948

Prior to this change `pipelineInitializationKey` would never be updated so `initialize` would always be called even if the pipeline didn't change
