OwnedPtr, SharedPtr: Add operator bool
Option, Result: Make try_move_value() non-const since it modifies the Option
kernel: Switch to a stack we control for the main task as soon as we leave early boot
Heap: Fix GPF caused when making many small allocations
Heap: Avoid accessing a block after it's potentially deleted
luna: Skip UBSAN.cpp in CMakeLists as that's not implemented yet
luna: Use spinlocks in the heap implementation
kernel, luna: Move Spinlock.h to luna
Option: Use __builtin_launder to ensure that the compiler doesn't label this as UB
SharedPtr: Implement make_shared using adopt_shared
SharedPtr: Delete ptr on failure in all adopt_shared* functions
