please review the following patch.
Bug: Add jtreg compiler tests to Hotspot JPRT jobs
Problem: The test/TEST.groups file lists JTREG compiler tests executed
in JPRT (target name: 'hotspot_compiler'). We need to determine the list
of tests from test/compiler that should be executed in JPRT. The total
time of execution should be less than 10 minutes on slowest platform.
Solution: The slowest platform in JPRT is currently solaris_sparcv9. I
executed all open JTREG tests from test/compiler on solaris_sparcv9 and
measured the "work time" of each test. Then, tests were sorted in
ascending order of their work time. To construct the subset, I first
added the test with the lowest work time to the subset and then
continued adding tests until a time limit L is reached.
Limit L is set to 80% of the original time budget (10 minutes). L is set
conservatively to account also for JPRT "cleanup", "init", and
"finishing" time, as well as for the variation of tests' "work time".
(The profiling measurements contain only "work time".)
The subset contains 77 tests. The longest executing test in the subset
takes 6.9 seconds.
Testing: Ran subset on all platforms in both west and stockholm JPRT.
Execution times of tests are as follows:
linux_i586-fastdebug-c1-hotspot_compiler success(03m 01s)
linux_i586-fastdebug-c2-hotspot_compiler success(03m 39s)
linux_x64-fastdebug-c2-hotspot_compiler success(03m 32s)
macosx_x64-fastdebug-c2-hotspot_compiler success(03m 48s)

We get close to the 10 minute budget (87% usage on West for
