[PATCH] Fix Shark build in JDK9

I'm CC-ing hotspot-dev for review of Hotspot code related changes.
Yes, some additional changes to Hotspot are required. This is the full
set of changes needed to build and run Shark:
- In the Makefile fix a typo to be able to build unzipped debuginfo.
- In ciTypeFlow.cpp only include some files and code only when building
C2. I don't think that code makes sense outside of C2. (That's the issue
that you've seen).
- In systemDictionary.cpp, exclude some code for Shark that creates and
checks native wrappers for method handle intrinsics. Invokedynamic stuff
is not yet implemented in Shark, so we can't do this.
- In allocation.hpp, exclude the operator overrides for new etc, LLVM
does allocations itself, and this would blow up.
- In handles.hpp and handles.inline.hpp, I added an argument
check_in_stack so that I can disable the in-stack check for the
SharkNativeWrapper. The SharkNativeWrapper is allocated on-heap and the
methodHandle inside the SharkNativeWrapper. I could have excluded that
check altogther using an #ifndef SHARK, but the way I implemented it
seemed more finegrained.
- In SharkCompiler, I pulled out the code to initialize LLVM into its
own method, and the call to set_state(initialized) out of the
execution-engine-lock. This would otherwise complain about wrong
- In SharkRuntime, I changed the cast from intptr_t to oop to work with
the new picky compilers ;-)
Thanks and best regards,
