LLVMJIT: Release JIT context after running ExprContext shutdown callbacks.

Due to inlining it previously was possible that an ExprContext's
shutdown callback pointed to a JITed function. As the JIT context
previously was shut down before the shutdown callbacks were called,
that could lead to segfaults.  Fix the ordering.
