re PR c/59984 (OpenMP pragma makes loop incorrect)
PR c/59984
* gimplify.c (gimplify_bind_expr): In ORT_SIMD region
mark local addressable non-static vars as GOVD_PRIVATE
instead of GOVD_LOCAL.
* omp-low.c (lower_omp_for): Move gimple_bind_vars
and BLOCK_VARS of gimple_bind_block to new_stmt rather
than copying them.
* gcc.dg/vect/pr59984.c: New test.
