check leftover FIXMEs in r2018
A number of FIXME entries were left behind (late merge, quite heavy last-minute testing/fixing), some related to PME GPU, others not. We should check and eliminate these asap in the master branch unless they hide bugs.
A similar check could be done for leftover TODOs.

Some of these are clear candidates to look at:

There is nothing critical in the PME ones, just some ugliness and leftovers. I treated "FIXME" as a "TODO with slightly higher priority" :-)
The last 2 lines are removed in the chain that re-enables separate PME rank tests, up from https://gerrit.gromacs.org/#/c/7469/.
BTW, grepping release-2016 diff for FIXME gives 19 results, while grepping for TODO - 382.

That was about HostAllocationPolicy residing in gpu_utils instead of utility.
Actually, shouldn't gpu_utils be a part of utility?
Not even sure if "util*" is a fitting description for such basic building blocks.
There's some need to reconsider what is in utility. (There was some discussion about its interaction with the SIMD module for a SIMD-suitable array view.)There's cases for separating
- a module of low-level things used in many places (memory, error handling, logging, strings, assertions, exceptions, mutex, variant, regex; timing we already separated)
- a module of miscellaneous things used rarely (pretty printing, version reporting)
- a module for stream or I/O or serialization support
- a module for key-value tree support
- a module for GPU operation support (transfers, launches)
Some things in gpu_utils might make sense in the "low level things," some not.
