Test code/infrastruture should use DYLD_LIBRARY_PATH on OSX JDK11

[babsingh]

The following tests are failing in #3603 ... Sanity - JDK11 - osx_x86-64_cmprssptrs:

16:49:38 ---SUMMARY OF FAILED TESTS---
16:49:38 abort  
16:49:38 softwareFloat  
16:49:38 hardwareFloat  
16:49:38 softwareRead  
16:49:38 hardwareRead

16:49:38 softwareFloat thread
16:49:38 hardwareFloat thread
16:49:38 softwareRead thread
16:49:38 hardwareRead thread

The reason for the above test failures is UnsatisfiedLinkError:

16:49:18  [ERR] Exception in thread "main" java.lang.UnsatisfiedLinkError: gptest (Not found in java.library.path)
16:49:18  [ERR] 	at java.base/java.lang.ClassLoader.loadLibraryWithPath(ClassLoader.java:1678)
16:49:18  [ERR] 	at java.base/java.lang.ClassLoader.loadLibraryWithClassLoader(ClassLoader.java:1648)
16:49:18  [ERR] 	at java.base/java.lang.System.loadLibrary(System.java:559)
16:49:18  [ERR] 	at VMBench.GPTests.GPTest.<clinit>(GPTest.java:70)

To fix the above test failures, test infrastructure needs to set DYLD_LIBRARY_PATH on MacOSX instead of LD_LIBRARY_PATH.

Before tests would hang at Test: abort stage on OSX. To reproduce the above failures locally, you will need the commits in #3603.

@sophia-guo Could you update the lib path for osx? Could you also check if we can use JDK_IMPL instead of JCL_VERSION in if statement. Thanks

Talked with Sophia, I will work on this issue

[babsingh]

UnsatisfiedLinkError failures are specific to OSX JDK11. With OSX JDK8, gpTest suite failures are different: gpTest suite failures on OSX with JDK8.

Tests are updated to use DYLD_LIBRARY_PATH on osx in #3765

Since cmdLineTest_gpTest hangs at abort test, it is excluded in #3765.

#3765 is the fix for this issue. Closing this issue since the following exception is no longer seen while running the gpTest suite:

16:49:18  [ERR] Exception in thread "main" java.lang.UnsatisfiedLinkError: gptest (Not found in java.library.path)
16:49:18  [ERR] 	at java.base/java.lang.ClassLoader.loadLibraryWithPath(ClassLoader.java:1678)
