Don't use ConcurrentHashMap.computeIfAbsent for typeOf cache,
because the computation may call typeOf recursively for different type
(e.g. C enum var type computation calls typeOf for enum base integer type),
which might cause a deadlock in computeIfAbsent.
48a684c0 added custom LLVM diagnostic handler, using JvmCallbacks machinery,
thus triggered a bug in the latter: callbacks are cached and outlive the compilation session,
but rely on memory that is reclaimed at the end of the compilation session.
So during a subsequent compilation in the same process (e.g. when the compiler runs in the
Gradle daemon process), LLVM might call the callback which accesses the reclaimed memory,
which in turn causes the crash.
Fix this by forcing JvmCallbacks to allocate memory that doesn't "expire" at the end of the compilation session.
Including
* Support thread state switching in codegen
* Introduce and use GCUnsafeCall annotation
* Switch thread state in C++ runtime code
Also
* Register current thread in Mark&Sweep tests
* Store MemoryState in Worker instance
* Set worker tid in WorkerInit
These annotations can be used on Objective-C property accessors imported
to Kotlin.
Note: the annotations aren't used in source code, only generated
directly to metadata by cinterop. So this commit doesn't in fact fix
anything but rather makes the implementation less fragile.

I was forced to manually do update the following files, because otherwise
they would be ignored according .gitignore settings. Probably they
should be deleted from repo.
