RFR: 8265421: java/lang/String/StringRepeat.java test is missing a memory requirement

[Christoph Göttschkes]

Please review the following patch, which fixes the mentioned test case for memory constrained devices. This can be tested on a linux based development machine, using systemd as follows:


$ systemd-run --user --scope -p MemoryMax=800M -p MemorySwapMax=0 /usr/bin/make TEST="test/jdk/java/lang/String/StringRepeat.java" run-test


I split up the test case in a part which only executes the small repeat counts, and in one part which executes the huge repeat count. The second part is guarded by a requirement, so it is only executed if enough memory is available.

-------------

Commit messages:
 - Adds a second test instance which executes the huge repeat count.
