jdk9 (fastdebug) build failed with gcc version 4.4.7-16

[KUBOTA Yuji]

Hi everyone,

I just cloned jdk9/dev and built fastdebug, then failed as similar as
JDK-8047382 [1].

/mockbuild/jdk9/dev/hotspot/src/share/vm/services/classLoadingService.cpp:
In static member function 'static void
ClassLoadingService::notify_class_loaded(InstanceKlass*, bool)':
/mockbuild/jdk9/dev/hotspot/src/share/vm/services/classLoadingService.cpp:147:
error: cannot reload integer constant operand in 'asm'
/mockbuild/jdk9/dev/hotspot/src/share/vm/services/classLoadingService.cpp:147:
error: cannot reload integer constant operand in 'asm'
gmake[8]: *** [classLoadingService.o] Error 1

As Lois said at JDK-8047382 [1], the HS_DTRACE_PROBE# macros
has been removed in JDK9. However, similar macros has came back
by JDK-7098194 [2], then failed when we used specified gcc version.
So I create a patch to fix it.

Should I create a new issue at JBS, or wait to remove the macros again?
