While merging the patch in a 3.4.3 based branch, I noticed three small issues:
- The rest_of_handle_life prototype in passes.c is not necessary. It is a
vestige from a previous (more intrusive) attempt to provide life
information to if_convert.
- In passes.c:rest_of_handle_if_conversion, at the end of the
flag_expensive_optimizations code, EXIT_BLOCK_PTR->global_live_at_start
has to be cleared for compatibility with this patch:

* cse.c (trivially_dead_nonlocal_regs): New variable.
(note_dead_set): New function.
(delete_trivially_dead_insns): If life info is available, update it.
For completeness, we might also clear ENTRY_BLOCK_PTR->global_live_at_end.
- config/pa/pa.c:pa_commutative_p is missing the parameter list:
(rtx x, int outer_code)
