[NFC][Assignment Tracking] Remove lifetime intrinsics from some tests
Browse files Browse the repository at this point in the history 
The intrinsics don't add anything to the tests and the tests are easier to
debug without the additional noise.

Some SSA value names have changed as a result of no longer visiting the
intrinsics.
