[15] RFR(T) 8242370: Enable JFR TestGCPhaseConcurrent test for Shenandoah

[Stefan Karlsson]

Hi Zhengyu,

Unfortunately, this patch breaks the dispatching of the tests if the 
user specifies the the GC to test.

For example:
makec ../build/fastdebug test 
TEST=test/jdk/jdk/jfr/event/gc/detailed/TestGCPhaseConcurrent.java 
JTREG="JAVA_OPTIONS=-XX:+UseZGC"

Will try to run the Shenandoah run line with both -XX:+UseZGC and 
-XX:+UseShenandoahGC.

You need to split this up into separate run like this:
https://cr.openjdk.java.net/~stefank/8242370/webrev.01/

Thanks,
StefanK
