RFR: 8153782: [JVMCI] update JVMCI sources to Eclipse 4.5.2 format style

[Doug Simon]

Eclipse 4.5 code formatting is not backward compatible with Eclipse 4.4 (“Luna”) (http://eclipse-n-mati.blogspot.ch/2015/06/eclipse-mars-how-to-switch-back-to.html). And only Eclipse 4.5 will have jdk9 support. This change updates the JVMCI code base such that the `mx eclipseformat` command can use Eclipse 4.5 to ensure consistent code format in JVMCI.
