re PR middle-end/66429 (ICE in expand_GOMP_SIMD_LAST_LANE)

	PR middle-end/66429
	* omp-low.c (expand_omp_taskreg, expand_omp_target): Use child_cfun
	instead of DECL_STRUCT_FUNCTION (child_fn).  Or in has_simduid_loops
	and has_force_vectorize_loops flags from cfun into
	child_cfun.
	(expand_omp_simd): For broken loop, set cfun->has_simduid_loops
	if simduid is non-NULL.
	* tree-pass.h (make_pass_simduid_cleanup): New prototype.
	* passes.def (pass_simduid_cleanup): Add new pass after loop
	passes.
	* tree-vectorizer.c (adjust_simduid_builtins): Remove one unnecessary
	indirection from htab argument's type.
	(shrink_simd_arrays): New function.
	(vectorize_loops): Use it.  Adjust adjust_simduid_builtins caller.
	Don't call adjust_simduid_builtins if there are no loops.
	(pass_data_simduid_cleanup, pass_simduid_cleanup): New variables.
	(pass_simduid_cleanup::execute): New method.
	(make_pass_simduid_cleanup): New function.
