--- Description ---
During an exp-run for llvm 14 (see bug 261742), it turned out that
java/openjdk13 and java/openjdk17 fail to build with clang 14 (but this also
affects openjdk14 through 16):

   ... (rest of output omitted)

Although the warning is normally an indication of a potential problem, in this
case a comment just before the affected code explictly mentions the reason for
using bitwise '|' instead of logical '||':

      // Process all available work on each (outer) iteration, rather than
      // only the first recognized bit of work, to avoid frequently true early
      // tests from potentially starving later work.  Hence the use of
      // arithmetic-or to combine results; we don't want short-circuiting.

(See
https://github.com/openjdk/jdk/blob/master/src/hotspot/share/runtime/serviceThr
ead.cpp#L140
)

Therefore, we should suppress -Wbitwise-instead-of-logical for clang 14 and
higher.
