20811 * omp-low.c (expand_omp_taskreg, expand_omp_target): Use child_cfun
20812 instead of DECL_STRUCT_FUNCTION (child_fn). Or in has_simduid_loops
20813 and has_force_vectorize_loops flags from cfun into
20815 (expand_omp_simd): For broken loop, set cfun->has_simduid_loops
20816 if simduid is non-NULL.

20821 indirection from htab argument's type.
20822 (shrink_simd_arrays): New function.
20823 (vectorize_loops): Use it. Adjust adjust_simduid_builtins caller.
20824 Don't call adjust_simduid_builtins if there are no loops.
20825 (pass_data_simduid_cleanup, pass_simduid_cleanup): New variables.
