Amber test exposing the problem

Running the attached test using Amber (<a href="https://github.com/google/amber">https://github.com/google/amber</a>):

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)
Device: Intel(R) HD Graphics 630 (Kaby Lake GT2)</pre>
