    Bug 20729: Fix building with -Os.

    This commit adds a new DIAG_IGNORE_Os_NEEDS_COMMENT which is only
    enabled when compiling with -Os. This allows developers working on
    -Os enabled builds to mark false-positive warnings without impacting the
    warnings emitted at -O2.

    Then using the new DIAG_IGNORE_Os_NEEDS_COMMENT we fix 6 warnings
    generated with GCC 5 to get -Os builds working again.
