Request for review (S): JDK-8002169: TEST_BUG: compiler/7009359/Test7009359.java sometimes times out

[Krystal Mo]

Hi all,

Could I have a review on this small change, please?

Webrev: http://cr.openjdk.java.net/~kmo/8002169/webrev.00/
Bug: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=8002169

The test may run into timeout easier if it were ran on the client 
compiler (whereas the test was only meant to test the server compiler).
To make it less prone to timeout, I did the following changes:
1. instead of excluding main() from compiling, specify stringmakerBUG() 
as dontinline in the CompileCommand, so that stringmakerBUG() will still 
be compiled into its own native code whereas main can run much faster.
2. decrease the number of test loop iterations from 1000000 to 100000

Testing with JPRT,
and tested this version of the test with JDK7b124 which didn't have the 
fix for 7009359 and verified the bug can still reproduce.

$ javac Test7009359.java
$ ./jdk1.7.0/fastdebug/bin/java -version
java version "1.7.0-ea-fastdebug"
Java(TM) SE Runtime Environment (build 1.7.0-ea-fastdebug-b124)
