JDK-8301998 - Update HarfBuzz to 7.0.1
Description
We see a lot of errors

/jdk-dev/src/java.desktop/share/native/libharfbuzz/hb-algs.hh:882:10: error: 1540-2993 The builtin "__builtin_mul_overflow" is not supported.

Seems xlC sets the clang related macros, so we run into  __builtin_mul_overflow , we might need to avoid this and add special handling for AIX 

878  #if (defined(__GNUC__) && (__GNUC__ >= 4)) || (defined(__clang__) && (__clang_major__ >= 8))
879    unsigned stack_result;
880    if (!result)
881      result = &stack_result;
882    return __builtin_mul_overflow (count, size, result);
883  #endif

Hi [~mdoerr] we use this version of xlC16: configure: Using xlc C compiler version 16.1.0 [IBM XL C/C++ for AIX, V16.1.0 (5725-C72, 5765-J12) Version: 16.01.0000.0013]
