    The fix for 8254790 needs to be backported to JDK11u.
    The fix is one-line change in string_indexof_char intrinsic.
    The intrinsic is moved to c2_MacroAssembler_x86.cpp since jdk15 and was in macroAssembler_x86.cpp in JDK 11u so I am sending a separate webrev review request.
    The other stringL_indexof_char intrinsic didn't exist in JDK11u so that fix is omitted in this webrev.
