RFR: 8265421: java/lang/String/StringRepeat.java test is missing a memory requirement [v2]

[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.

Christoph Göttschkes has updated the pull request incrementally with one additional commit since the last revision:

  Removes -Xmx2g for the first test case instance, which doesn't require a lot of memory.
