RFR: JDK-8157141 & JDK-8166454: Solaris getisax(2) and meminfo(2) cleanup

[Vladimir Kozlov]

I missed all this review fun :)

Thank you, Alan, for cleaning this up.

The only concern I have is removal of conditional macros.

Most likely people will try to run JDK 9 on Solaris 10. Or in some kind 
of VM environment which may not have Solaris 11.1 headers. We have a lot 
such cases before that is why those macros were added.

"JDK 9 Platform Support" list only Solaris 11.x and 12.x. May be it is 
fine but original code would cover more running cases.

Sorry for rumbling.

Regards,
Vladimir
