Gtest for 8241581 got added accidentally after running all tests but before the push. Immediate result is an escaped build error in release:

/shared/projects/openjdk/jdk-jdk/source/test/hotspot/gtest/utilities/test_bitMap_popcnt.cpp: In destructor 'ErrorDetailsPrinter::~ErrorDetailsPrinter()':
/shared/projects/openjdk/jdk-jdk/source/test/hotspot/gtest/utilities/test_bitMap_popcnt.cpp:96:11: error: 'class BitMap' has no member named 'print_on'

but since there may be other errors on non-tested platforms as well, I'd like to remove the test for now. The tested functionality is still unused, so we need not to roll-back the whole patch.
