[jdk11u-dev] RFR: 8139046: Compiler Control: IGVPrintLevel directive should set PrintIdealGraph

[Martin Doerr]

Backport of [JDK-8139046](https://bugs.openjdk.java.net/browse/JDK-8139046)
Doesn't apply cleanly:

- compile.hpp: Had to take `should_print` from https://github.com/openjdk/jdk/commit/75e9d0a2901c149fc0acf3ed042ddedc689d8d23
- compilerDefinitions.cpp, compile.cpp, idealGraphPrinter.cpp, idealGraphPrinter.hpp: Had to do resolve hunks manually.
