* tree-ssa-operands.h (create_ssa_artificial_load_stmt): Add
parameter to say whether to unlink immediate uses.
* tree-ssa-operands.c (create_ssa_artificial_load_stmt): Do not
mark the artificial stmt as modified. Unlink immediate uses
only if requested.
* tree-ssa-dom.c (record_equivalences_from_stmt): Update caller.
* tree-ssa-pre.c (insert_fake_stores): Likewise.
* gcc.c-torture/compile/20071214-1.c: New testcase.
