Dear all,

please review and sponsor this (large, sorry) change.

RFE: https://bugs.openjdk.java.net/browse/JDK-8075492
Webrev: http://cr.openjdk.java.net/~mhaupt/8075492/webrev.00

The IGV version in the hs-comp repository - and consequently in OpenJDK - currently dates back to 2010. This change brings it up to date; essentially copying the source from the Graal repository over to hs-comp. In the process of doing so, the control flow window and basic block layout feature that existed in another outdated IGV repository on Kenai was also brought back to Graal's IGV, and is now part of this proposed change.

Only manual testing was applied. There are minor changes in HotSpot, which are only in code pertaining to IdealGraphPrinter. Thanks to Roland Westrelin and Doug Simon for helping with the testing.
