Re-do the way locking is done during verification
We now lock at the "leaves" on the types, rather than locking at references.
In particular, Validate for sth. of non-reference lvalue will also lock the "outer" memory.
Also change the way we release write locks, and some refactoring in the memory.

add locking data structures and lock checks
This brings back some of the memory range ideas that were deleted with the packed refactoring.

72664e42aa No longer check aligment and non-NULLness on &
This breaks creating unaligned raw pointers via `&packed.field as *const _`, which needs to be legal.
Also it doesn't seem like LLVM still relies on this, see
* https://github.com/solson/miri/issues/244#issuecomment-315563640
* https://internals.rust-lang.org/t/rules-for-alignment-and-non-nullness-of-references/5430/16

We probably want to handle this invariant like the others that validation is concerned with, and only
check it on function boundaries for now.
