[patch] pr18181 fix: part1

[Dorit Naishlos <DORIT at il dot ibm dot com>]

Cleanup towards pr18181 fix (part 1):

Make a clearer separation between the peeling functions and the
vectorization functions:
1. Moved around function declarations,
2. Added prefix "slpeel" for the peeling functions (stands for "simple loop
peeling").

ok?

Changelog:

        * tree-vectorizer.c (slpeel_tree_peel_loop_to_edge): New name for
        function previously called tree_duplicate_loop_to_edge.
        (slpeel_tree_duplicate_loop_to_edge_cfg): New name for function
        previously called tree_duplicate_loop_to_edge_cfg.
        (slpeel_update_phis_for_duplicate_loop): Prefix 'slpeel' added to
        function name.
        (slpeel_update_phi_nodes_for_guard): Likewise.
        (slpeel_make_loop_iterate_ntimes): Likewise.
        (slpeel_add_loop_guard): Likewise.
        (allocate_new_names, free_new_names): Function declaration moved to
top
        of file.
        (rename_use_op, rename_def_op): Likewise.
        (rename_variables_in_bb, rename_variables_in_loop): Likewise.
        (vect_generate_tmps_on_preheader): Function declaration moved.
        (vect_transform_for_unknown_loop_bound): Added missing function
        declaration.
