* tree-mudflap.c (insert_edge_copies_seq): Copied here from tree-sra.c
* tree-sra.c (sra_type_can_be_decomposed_p): Made static.
(sra_insert_before): Likewise.
(sra_insert_after): Likewise.
(sra_init_cache): Likewise.
(insert_edge_copies_seq): Made static and moved upwards.
* tree-complex.c (extract_component): Added VIEW_CONVERT_EXPR switch
case.
* tree-flow-inline.h (contains_view_convert_expr_p): New function.
* ipa-prop.c (get_ssa_def_if_simple_copy): New function.
