RFR (S): 7197424: update copyright year to match last edit in jdk8 hotspot repository

[Mikael Vidstedt]

All,

Can I please get a couple of reviews of the below change?

Don't be scared by the size of the change, even though it touches many 
files (271 to be exact) the change is the same for all of them - 
updating the copyright year in the header. The change was created using 
the make/scripts/update_copyright_year.sh script from the JDK.

Thanks,
Mikael
