Amber test exposing the problem
Running the attached test using Amber (https://github.com/google/amber):
amber do-while-loop-in-conditionals.amber
should lead to the test passing.
Instead, an assertion fails:
amber: ../src/compiler/nir/nir_opt_remove_phis.c:115: remove_phis_block:
Assertion `def != NULL' failed.
Build: Mesa 19.2.0-devel (git-243db4980c) (Debug)
