I've first separately pushed the mostly "mechanical changes" re
"[OpenACC] Extract 'pass_oacc_loop_designation' out of
'pass_oacc_device_lower'" to master branch in commit
0829ab79d37be6c59072af0c4f54043f7e9d23ea, see attached.

Sneaky.  ACK.

This does not just OpenACC loop designation but also includes the general
OpenACC offloaded function classification (diagnostics) as well as
OpenACC 'nohost' clause handling for OpenACC 'routine', meaning that the
"loop designation" name is not totally accurate.  But I couldn't easily
come up with anything more accurate (or an easy way to split out these
things), so I left it at that.

(Also, for later, I wonder if not all the 'oacc_loop' stuff could/should
move into its own new file 'gcc/omp-oacc-loop.cc'.  Also, the tag
'oacc_loop' isn't totally accurate either, for this also deals with
OpenACC 'routine' level of parallelism -- maybe 'oacc_lop' instead of
'oacc_loop' etc.)

I do confirm the manual 'calculate_dominance_info (CDI_DOMINATORS)'
necessary in the original state (where this is in the middle of the two
"passes"), but given 'TODO_cleanup_cfg' as part of 'todo_flags_finish'
for new 'pass_oacc_loop_designation', we no longer need that now, as far
as I can tell.  So I removed the manual
'calculate_dominance_info (CDI_DOMINATORS)' -- but please do tell if
there is a reason to keep it.

Do you remember why you added 'TODO_rebuild_alias' here?
'pass_oacc_device_lower' doesn't have it, and neither does
'pass_oacc_loop_designation' in your original (2017-11-27) internal
gcn/master branch commit 81ee7ef64cdfa47c01f24c79b8ebd03242c9f3eb
"Split device-lowering/gimple workers into three passes".  So I
removed that -- but please do tell if there is a reason to keep it.

I do not :-). My suspicion is that it was leftover debug code, or
possibly the result of a bad merge.

(Another possibility is that the alias information needs updating when
we change the address space of certain entities during gimple rewriting
for worker partitioning -- but this is the wrong place for that, I
think?).

Thanks,

Julian
