           Summary: Launching SteamVR results in
                    nir_deref_instr_remove_if_unused assert
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW

When launching SteamVR, the vrcompositor process hits the following assert:

vrcompositor: ../src/compiler/nir/nir_deref.c:95:
nir_deref_instr_remove_if_unused: Assertion `d->dest.is_ssa' failed.

This regression started with the change:
864c78 "nir/opt_if: Re-materialize derefs in use blocks before peeling loops"
