    [WPE][GTK] Crash in WebCore::TextDecorationPainter::paintBackgroundDecorations when compiled with Clang with LTO enabled
    https://bugs.webkit.org/show_bug.cgi?id=274780

    Reviewed by Michael Catanzaro.

    Clang seem to have some issue when inlining assignment and move
    operators in LTO builds, generating code that tries to perform OOB
    access to Vector data. Replacing an assignmenmt with a Vector::swap(),
    which is semantically equivalent in this case (the moved-from object
    is not used again in the function) workarounds the compiler issue.
