RFR: 8281614: serviceability/sa/ClhsdbFindPC.java fails with java.lang.RuntimeException: 'In code in NMethod for jdk/test/lib/apps/LingeredApp.steadyState' missing from stdout/stderr [v2]

[Chris Plummer]

> This test has 4 test cases/modes: two core files test cases and two process. Each runs with and w/o `-Xcomp`. The `-Xcomp` test cases are not suppose to run when `-XX:+DeoptimizeALot` is used, because the test does some checks that assume certain methods will be compiled. This is handled by adding the following to the test case:
> 
> ` * @requires vm.opt.DeoptimizeALot != true`
> 
> When this was first added, only the process test cases existed. Later on the core tests cases were added, and the `@requires` was copied improperly. It ended up with `#no-xcomp-process` rather than `#xcomp-core`, which allows the `#xcomp-core` test case to run even when `-XX:+DeoptimizeALot` is being used.

Chris Plummer has updated the pull request incrementally with one additional commit since the last revision:

  Move @requires for Xcomp to the correct test case.
