RFR: 8159590: Remove deprecated methods from jdk.internal.misc.VM

[Claes Redestad]

Hi,

after VM.java was encapsulated and moved from sun.misc to 
jdk.internal.misc, the rationale for keeping a number of deprecated 
methods and constants no longer applies and these methods should be removed:

Webrev: http://cr.openjdk.java.net/~redestad/8159590/webrev.01/
Bug: https://bugs.openjdk.java.net/browse/JDK-8159590

This falls somewhere between an enhancement and a bug fix, so feel free 
to object to or endorse treating this as a bug. :-)
