re PR middle-end/19551 (pure (complex types) function call removed as dead (LAPACK routine claic1.f bug))

* flow.c (propagate_one_insn): Formatting.

PR middle-end/19551
* flow.c (libcall_dead_p): Be more conservative if unsure.
If there are any instructions between insn and call, see if they are
all dead before saying the libcall is dead.

* gcc.c-torture/execute/20050121-1.c: New test.
