[10] RFR (XS) 8185900: hotspot build failed with gcc version Red Hat 4.4.7-3

Could I get reviews for this hotspot build issue, please?

Some versions of GCC, for example GCC 4.4.7, fail to compile hotspot
with dtrace probes compiled in on Linux. The issue is *very* similar to
JDK-8047382 which got classified as 9-na, which I believe was
incorrect. DTRACE_CLASS* macros need similar treatment in JDK 10 and
subsequently 9.

Since the changed files are shared, I'd need a sponsor please.

Bug: https://bugs.openjdk.java.net/browse/JDK-8185900
webrev: http://cr.openjdk.java.net/~sgehwolf/webrevs/JDK-8185900/webrev.01/

Testing: JDK 10 hotspot now builds on RHEL-6 with dtrace on (-DDTRACE_ENABLED).
         Failed previously.
