Please review at your convenience.
Issue: https://bugs.openjdk.java.net/browse/JDK-8140630
Patch: Included below
The change is to compile src/java.base/share/native/libjava/Bits.c only into
libjava.so with normal optimization level (-O2) instead of high optimization
level (-O3). The other objects in libjava are not affected. This is for 64-bit
Linux only. With this patch applied, java/nio/Buffer/Basic.java now passes on
all platforms and there is no crash.
Thanks,
Brian
