src/aix/porting/porting_aix.* are moved to src/java.desktop/aix/native/libawt/porting_aix.*.

Since AIX hprof also requires dladdr, currently porting_aix.* are copied to src/demo/aix/jvmti/hprof.

However, jdk/make/CompileDemo.gmk will need adjustment to include this tiny function in libhprof.

# On AIX, hprof requires 'dladdr' from src/aix/porting/porting_aix.cpp
