RFR 8161696 [TESTBUG] runtime/StackGuardPages/testme.sh uses invalid argument -Xss328k

[Gerald Thornbrugh]

Hi Everyone,

I would like to have the following change reviewed:

Bug: https://bugs.openjdk.java.net/browse/JDK-8161696

Webrev:http://cr.openjdk.java.net/~gthornbr/8161696/hotspot-webrev.01/ 
<http://cr.openjdk.java.net/%7Egthornbr/8161696/hotspot-webrev.01/>

The stack size for this test needs to be increased to 384K for some 
platforms.
My fix for JDK-8081770 https://bugs.openjdk.java.net/browse/JDK-8081770 
moved the functionality
from the testme.sh script to exeinvoke.c so the dependency for a local 
compiler could be removed.
Because of this the stack size change needs to be applied to exeinvoke.c 
file instead of the testme.sh file.

Please let me know if you have any questions or concerns.

Thanks,

Jerry
