[PR] [Relax] Identify tuple unpack/repack in CanonicalizeBindings [tvm]

["Lunderberg (via GitHub)" <gi...@apache.org>]

Lunderberg opened a new pull request, #17313:
URL: https://github.com/apache/tvm/pull/17313

   Prior to this commit, the `CanonicalizeBindings` pass could identify and simplify a value that had been packed into a tuple, then extracted from it.  (e.g. Simplifying `tup = (x,y); z = tup[0]` into `z = x`.)  However, it could not identify a value that had been expanded from a tuple, and then re-bundled.  (e.g. Simplifying `new_tuple = (tup[0], tup[1])` into `new_tuple = tup`.)
   
   This commit updates `CanonicalizeBindings` to identify and remove unnecessary tuple unpacking/repacking.
