RFR[T, urgent]: 8241723: Build error after 8241581

[Thomas Stüfe]

Hi,

not my proudest day.

<https://bugs.openjdk.java.net/browse/JDK-8241723>
Gtest for 8241581 got added accidentally after running the 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 in this gtest as well, I'd like to
remove the test, re-run all tests, then re-add it.

The tested functionality is still unused, so we need not to roll-back the
whole patch.

Fix consists of "hg
remove test/hotspot/gtest/utilities/test_bitMap_popcnt.cpp", so there is no
webrev.

Thanks, Thomas
