* frontend-passes.c (optimize_op): Change
old-style comparison operators to new-style, simplify
switch as a result.
(empty_string): New function.
(get_len_trim_call): New function.
(optimize_comparison): If comparing to an empty string,
use comparison of len_trim to zero.
Use new-style comparison operators only.
(optimize_trim): Use get_len_trim_call.
