[PATCH] D70321: Make it possible to add the MIR Canonicalizer pass in a pipeline

[Aditya Nandakumar via Phabricator via llvm-commits]

aditya_nandakumar created this revision.
aditya_nandakumar added reviewers: plotfi, bogner.
Herald added a project: LLVM.

Allow the pass to be added in a pipeline (for debugging purposes).
Alternatively we can separate the MIRCanonicalizer pass into a header, and not need to add the ID here.
