Ian Romanick d52a423f60 nir/gcm: Clear out pass_flags before starting
With this pass enabled in Intel drivers, running shader-db on
shaders/unity/38.shader_test resulted in

Program received signal SIGSEGV, Segmentation fault.
gcm_schedule_early_src (src=0x555555d45348, void_state=0x7fffffffba40) at ../../SOURCE/master/src/compiler/nir/nir_opt_gcm.c:297
297	   if (info->early_block->index < src_info->early_block->index)
(gdb) print src_info->early_block
$1 = (nir_block *) 0x0

I tracked this down to an early exit from gcm_schedule_early_instr on
the parent instruction because instr->pass_flags was 0x1c.  That
should be an impossible value for this pass, so I inferred that
pass_flags must have dirt left from some previous pass.

Fixes: 8dfe6f672f ("nir/GCM: Use pass_flags instead of bitsets for tracking visited/pinned")

  $ meson ..
  $ sudo ninja install

necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
