Stefan Gränitz 9ce0641199 [Kaleidoscope] Fix race condition in order-of-destruction between SectionMemoryManager and its MemoryMapper ...

SectionMemoryManager's default memory mapper used to be a global static
object. If the SectionMemoryManager itself is a global static
object, it might be destroyed after its memory mapper and thus couldn't
use it from the destructor.

The Kaleidoscope tutorial reproduced this situation with MSVC for a long time.
Since 47f5c54f99 it's triggered with GCC as well. The solution from
this patch was proposed in the existing review https://reviews.llvm.org/D107087
before, but it didn't move forward.
