    Use gimple_build to perform conversion simplification

    The following uses gimple_build to do the conversion simplification
    in build_and_insert_cast instead of duplicating it there.  Conveniently
    when building directly into the IL all stmts are taken into account
    for the simplification.

            * tree-ssa-math-opts.cc (build_and_insert_cast): Remove
            conversion simplification, instead use gimple_convert.
