re PR middle-end/28436 (accessing an element via a "pointer" on a vector does not cause vec_extract to be used)

PR tree-opt/28436
* tree.h (DECL_COMPLEX_GIMPLE_REG_P): Rename to ...
(DECL_GIMPLE_REG_P): This.
* fold-const.c (fold_indirect_ref_1): Fold *(foo *)&vectorfoo into
using BIT_FIELD_REF.
* omp-low.c (omp_copy_decl_2): Use the renamed DECL_GIMPLE_REG_P.
* tree-gimple.c (is_gimple_reg): Use the renamed DECL_GIMPLE_REG_P
and check for VECTOR_TYPE.
* expr.c (get_inner_reference): Set the mode for BIT_FIELD_REF with
vector types.
* tree-flow-inline.h (var_can_have_subvars): Use the renamed
DECL_GIMPLE_REG_P.
* gimplify.c (internal_get_tmp_var): Use the renamed DECL_GIMPLE_REG_P
and check for VECTOR_TYPE.
(gimplify_bind_expr): Likewise.
(gimplify_function_tree): Likewise.
* expmed.c: Include target.h.
(extract_bit_field): For vector mode, try find a better mode first.
If that fails use gen_lowpart (for vectors only).
* tree-dfa.c (make_rename_temp): Use the renamed DECL_GIMPLE_REG_P
and check for VECTOR_TYPE.
* tree-ssa-pre.c (create_expressions_by_pieces): Likewise.
(insert_into_preds_of_block): Likewise.
(insert_fake_stores): Create gimple register store_tmps for
vector types.
* tree-sra.c (sra_elt): New field, is_vector_lhs.
(sra_walk_expr <case BIT_FIELD_REF>): For vector types that
are the left hand side, set the element's is_vector_lhs to true.
(instantiate_element): For vector types which were on the left hand size, set DECL_GIMPLE_REG_P to false.
* tree-nested.c (create_tmp_var_for): Use the renamed DECL_GIMPLE_REG_P. * tree-inline.c (declare_return_variable): Use the renamed
DECL_GIMPLE_REG_P
and check for VECTOR_TYPE. (copy_decl_to_var): Use the renamed DECL_GIMPLE_REG_P.
(copy_result_decl_to_var): Likewise.
* tree-vect-transform.c (vect_get_new_vect_var): For vector types, create a gimple register variable.
(vect_permute_store_chain): Set DECL_GIMPLE_REG_P to true for the
vect_inter_* temp variables.
* Makefile.in (expmed.o): Update dependencies.
