HotSpot build failure with GCC 7.1.1

[Yasumasa Suenaga]

Hi all,

I tried to jdk10/hs on Fedora 26 x86_64 with GCC 7.1.1, however it was failed as below:
-------------------
/home/ysuenaga/OpenJDK/jdk10-hs/hotspot/src/share/vm/oops/array.hpp: In static member function 'static int Array<T>::size(int, int)':
/home/ysuenaga/OpenJDK/jdk10-hs/hotspot/src/share/vm/oops/array.hpp:138:12: error: there are no arguments to 'align_size_up' that depend on a template parameter, so a declaration of 'align_size_up' must be available [-fpermissive]
      return align_size_up(byte_sizeof(length, elm_byte_size), BytesPerWord) / BytesPerWord; // FIXME
             ^~~~~~~~~~~~~
/home/ysuenaga/OpenJDK/jdk10-hs/hotspot/src/share/vm/oops/array.hpp:138:12: note: (if you use '-fpermissive', G++ will accept your code, but allowing the use of an undeclared name is deprecated)

    ... (rest of output omitted)
-------------------

I think this failure is since JDK-8072061:
   http://hg.openjdk.java.net/jdk10/hs/hotspot/rev/731370f39fcd#l42.35

IMHO we can fix this error as below:
-------------------

Someone is working for this issue?
If not, I will file it to JBS and will send review request.


Thanks,
