JDK-8339849 introduced some macros (do_stub/do_blob) which changed the format of some calls ("C2 Runtime <x>"). Valhalla testing needs to be realigned to new naming convention:

compiler/valhalla/inlinetypes/TestArrays.java
compiler/valhalla/inlinetypes/TestBasicFunctionality.java
compiler/valhalla/inlinetypes/TestLWorld.java
compiler/valhalla/inlinetypes/TestLWorldProfiling.java

Additionally, opto/runtime.hpp/.cpp was realigned to the new naming conventions (_Java, _C, _Type) for Valhalla functions (e.g. "load_unkown_inline"). Drawing attention to it as it might need further review/work.
