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.

Reduce the chance of accidentally calling functions in CTFE 
previously miri had a check for const fn and other cases that
CTFE requires. Instead the function call is completely
processed inside the machine. This allows CTFE to have full
control over what is called and miri to not have useless
CTFE-checks in normal mode.

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.

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.
