The tier1 hotspot test group includes tier1_common which is:

tier1_common = \
  sanity/BasicVMTest.java \
  gtest/GTestWrapper.java \
  gtest/LockStackGtests.java \
  gtest/MetaspaceGtests.java \
  gtest/LargePageGtests.java \
  gtest/NMTGtests.java \
  gtest/WindowsProcessorGroups.java

But tier5 testing runs group hotspot_misc which is defined as:

hotspot_misc = \
  / \
 -applications \
 -vmTestbase \
 -:hotspot_compiler \
 -:hotspot_gc \
 -:hotspot_runtime \
 -:hotspot_serviceability \
 -:hotspot_containers

as this does not exclude gtest/* this means that the gtests in tier1_common are run under identical conditions in tier1 and tier5. This is a waste of testing resources.

Unclear what the right fix is. Maybe we need hotspot_gtest that gets included in tier1 and excluded from hotspot_misc?

Also note that the lists of gtests in tier1_common is only a subset of the available gtests.
