This broke bootstrap on all arches:
../../gcc/omp-offload.c: In function ‘unsigned int oacc_loop_auto_partitions(oacc_loop*, unsigned int, bool)’:
../../gcc/omp-offload.c:1255:18: warning: suggest parentheses around operand of ‘!’ or change ‘|’ to ‘||’ or ‘!’ to ‘~’ [-Wparentheses]
   if (assign && (!outer_assign | loop->inner))
                  ^~~~~~~~~~~~~

It isn't immediately clear what you wanted to do there,
but in order to quickly fix the bootstrap problem, I've committed
following patch.  If you meant something different (such as
  if (assign && !(outer_assign || loop->inner))
), please submit a fix for review and make sure to bootstrap and regtest it.

	* omp-offload.c (oacc_loop_auto_partitions): Use || instead of |
	to avoid warning.
