668491a892 Work on making validation test pass again
Turns out that tracking write locks by their lifetime is not precise enough,
but for now, we don't have an alternative.  Also, we need to force_allocate
what we acquire or else the memory will not be in the right state.

Split the alloc id address space into functions and normal allocs
instead of interleaving them as before.
The next step is to also separate out static memory into its own
address space.

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.
