Jakub Jelinek 804c0f35a6 openmp: OpenMP loop transformation support

This patch is largely rewritten version of the

patch set which I've promissed to adjust the way I'd like it but didn't
get to it until now.

Only the 5.1/5.2 tile/unroll constructs are supported, in various
places some preparations for the other 6.0 loop transformations
constructs (interchange/reverse/fuse) are done, but certainly
not complete and not everywhere.  The important difference is that
because tile/unroll partial map 1:1 the original loops to generated
canonical loops and add another set of generated loops without canonical
form inside of it, the tile/unroll partial constructs are terminal
for the generated loop, one can't have some loops from the tile or
unroll partial and some further loops from inside the body of that
construct.
The GENERIC representation attempts to match what the standard specifies,
so there are separate OMP_TILE and OMP_UNROLL trees.  If for a particular
loop in a loop nest of some OpenMP loop it awaits a generated loop from a
nested loop, or if in OMP_LOOPXFORM_LOWERED OMP_TILE/UNROLL construct
a generated loop has been moved to some surrounding construct, that
particular loop is represented by all NULL_TREEs in the
OMP_FOR_{INIT,COND,INCR,ORIG_DECLS} vector.
The lowering of the loop transforming constructs is done at gimplification
time, at the start of gimplify_omp_for.
I think this way it is more maintainable over magic clauses with various
loop depths on the other looping constructs or the magic OMP_LOOP_TRANS
construct.
Though, I admit I'm still undecided how to represent the OpenMP 6.0
loop transformation case of say:
  #pragma omp for collapse (4)
  for (int i = 0; i < 32; ++i)
  #pragma omp interchange permutation (2, 1)
  #pragma omp reverse
  for (int j = 0; j < 32; ++j)
  #pragma omp reverse
  for (int k = 0; k < 32; ++k)
  for (int l = 0; l < 32; ++l)
    ;
Surely the i loop would go to first vector elements of OMP_FOR_*
of the work-sharing loop, then 2 loops are expecting generated loops
from interchange which would be inside of the body.  But the innermost
l loop isn't part of the interchange, so the question is where to
put it.  One possibility is to have it in the 4th loop of the OMP_FOR,
another possibility would be to add some artificial construct inside
of the OMP_INTERCHANGE and 2 OMP_REVERSE bodies which would contain
the inner loop(s), e.g. it could be OMP_INTERCHANGE without permutation
clause or some artificial ones or whatever.

I've recently raised various unclear things in the 5.1/5.2/TRs versions
regarding loop transformations, in particular
https://github.com/OpenMP/spec/issues/3908
https://github.com/OpenMP/spec/issues/3909
(sorry, private links unless you have OpenMP membership).  Until those
are resolved, I have a sorry on trying to mix generated loops with
non-rectangular loops (way too many questions need to be answered before
that can be done) and similarly for mixing non-perfectly nested loops
with generated loops (again, it can be implemented somehow, but is way
too unclear).  The second issue is mostly about data sharing, which is
ambiguous, the patch makes the artificial iterators of the loops effectively
private in the associated constructs (more like local), but for user
iterators doesn't do anything in particular, so for now one needs to use
explicit data sharing clauses on the non-loop transformation OpenMP looping
constructs or surrounding parallel/task/target etc.
