possibly dead call from slsr_process_phi () to gimple_bb ()

[Prathamesh Kulkarni]

Hi,
I am trying to write a WIP patch to warn for dead function calls,
and incidentally it caught the following dead call to gimple_bb() from
slsr_process_phi () in gimple-ssa-strength-reduction.c:

 if (SSA_NAME_IS_DEFAULT_DEF (arg))
   arg_bb = single_succ (ENTRY_BLOCK_PTR_FOR_FN (cfun));
 else
   gimple_bb (SSA_NAME_DEF_STMT (arg));

Presumably it should be:
arg_bb = gimple_bb (SSA_NAME_DEF_STMT (arg)) ?

Thanks,
Prathamesh
