RFR JDK-8071501 perfMemory_solaris.cpp failing to compile with "Error: dd_fd is not a member of DIR."

[Gerald Thornbrugh]

Hi,

Please review my JDK8 and JDK9 fix for JDK-8071501 
perfMemory_solaris.cpp failing to compile with
"Error: dd_fd is not a member of DIR."

This compiler error occurs when Solaris 11 include files are used to 
build hotspot and the POSIX
version of the DIR structure is used in the build process.  The fix 
forces all Solaris builds to use
the same version of the DIR structure.

JDK8 Webrev: http://cr.openjdk.java.net/~gthornbr/fd/jdk8/webrev/

JDK9 Webrev: http://cr.openjdk.java.net/~gthornbr/fd/jdk9/webrev/
<http://cr.openjdk.java.net/%7Egthornbr/fd/jdk9/webrev/>
I have completed JPRT bulds and tests on platforms without issues.

Thanks,

Gerald
