ICEs when compiling the following testcase, reduced from
test/OpenMP/for_reduction_codegen_UDR.cpp from the clang 10.0.1 test suite, w/
-fopenmp:
enum omp_allocator_handle_t {
omp_cgroup_mem_alloc = 6,

struct pd {

d9 ()

int t7;
pd gy[1] = { pd(), };
#pragma omp for reduction (& : gy) allocate (omp_cgroup_mem_alloc: gy)
for (t7 = 0; t7 < 1; ++t7)
{
}
