    outputs.exp: conditionals for split-dwarf and lto plugin

    This patch introduces support for conditionals (and expr) expansions
    to file lists in proc outest in outputs.exp.

    The conditionals machinery is now used to guard files that are only
    created by the LTO plugin, or when not using the LTO plugin.

    It is also used to avoid special-casing .dwo files: the condition of
    when they're expected is now encoded in the list.

    Furthermore, the -g flag, that used to be specified along with
    $gsplit_dwarf, is now moved into $gsplit_dwarf, so that we don't
    compile with -g if -gsplit-dwarf is not needed.  This avoids having to
    deal with .dSYM directories.

    Further removing special cases, $aout is now dealt with in a more
    general way, using expr to perform variable/string expansion.

            * gcc.misc-tests/outputs.exp (gsplit_dwarf): Move -g into it.
            (outest): Introduce conditionals and string/variable/expr
            expansion.  Drop special-casing of $aout and .dwo.
            (gspd): New conditional.  Guard all .dwo files with it.
            (ltop): New conditional.  Guard files created by the LTO
            plugin with it.  Guard files created by fat LTO compilation
            with its negation.  Add a few -fno-use-linker-plugin tests
            guarded by it.
