tree.c (tree_vec_elt_check_failed): New function.
* tree.c (tree_vec_elt_check_failed): New function.
* tree.h (TREE_VEC_ELT_CHECK): New checking macro.
(TREE_VEC_ELT): Use it.
* tree-inline.c (optimize_inline_calls): Don't copy a
zero-length vector.
cp:
* search.c (dfs_push_decls): Do not try to reorder elements
3..n of method_vec if method_vec has only two elements.
Reverse order of two tests to avoid accessing unallocated
memory.
