Andrew, please, help Alexeev to file JBS bug and publish webrev on cr.openjdk. We can't review or accept patches which 
are not on cr. server.

There are several hotspot tests which check bitCount intrinsics (for example, 
compiler//codegen/6378821/Test6378821.java) but not full range of values.

Note, jdk tests should be run with -Xcomp to make sure methods are compiled and intrinsics are used.
