In java2d coding there are a few overflows (those are shown when running jtreg
tests with ubsan enabled binaries)
jtreg test java/awt/Scrollbar/AquaLFScrollbarTest/ScrollBarBorderTest.java shows
jdk/src/java.desktop/share/native/libawt/java2d/loops/TransformHelper.c:683:16:

There is currently no need seen to adjust this coding, so exclude the methods
from ubsan checking to avoid unneeded warnings.
