* expmed.c (const_mult_add_overflow_p): New.
* expr.h: Declare it.
* loop.c (maybe_eliminate_biv_1) [COMPARE]: Use it.

From-SVN: r54075
* flow.c (propagate_one_insn): Revise yesterday's patch. Delete
a dead insn with a REG_RETVAL note when the entire libcall is not
dead and remove the associated REG_LIBCALL note at the same time.

(compute_earliest): Remove hack to treat renumbered EXIT_BLOCK
as an ordinary block.

an ordinary block, or handle sucessors of entry block specially.
Instead, split edges from entry block and to exit block, and
put a computing definition on the thus gained post-entry-block,
and a need on the pre-exit-block.
