openmp: Support allocate for C/C++ array section reductions
This adds allocate clause support for array section reductions.
Furthermore, it fixes one bug that would cause inscan reductions with
allocate to be rejected by C, and for now just ignores allocate for
inscan/task reductions, that will need slightly more work.

gcc/
* omp-low.c (scan_sharing_clauses): For now remove for reduction
clauses with inscan or task modifiers decl from allocate_map.
(lower_private_allocate): Handle TYPE_P (new_var).
(lower_rec_input_clauses): Handle allocate clause for C/C++ array
reductions.
gcc/c/
* c-typeck.c (c_finish_omp_clauses): Don't clear
OMP_CLAUSE_REDUCTION_INSCAN unless reduction_seen == -2.
libgomp/
* testsuite/libgomp.c-c++-common/allocate-1.c (foo): Add tests
for array reductions.
(main): Adjust foo callers.
