Andreas Kling 2584636d19 Kernel: Fix partial munmap() deallocating still-in-use VM ...

We were always returning the full VM range of the partially-unmapped
Region to the range allocator. This caused us to re-use those addresses
for subsequent VM allocations.

This patch also skips creating a new VMObject in partial munmap().
Instead we just make split regions that point into the same VMObject.

This fixes the mysterious GCC ICE on large C++ programs.
