Bump default JVM args to maximum safe performance on JDK8

Assumed to be the common use case for someone who is compiling from
source:

  • Set encoding explicitly to UTF-8
  • Aggressively JIT all JVM methods after ten invocations
  • Explicitly use G1 garbarge collector
  • 64bits
  • Property svn:eol-style set to LF
  • Property svn:keywords set to Id
