5a7f4412ee Implement Eq and Hash for MemoryData and Evaluator 
In order to implement infinite loop detection while executing MIR, both
the implementor of `Machine` (`Evaluator`) and its associated type
(`MemoryData`), must implement `Eq` and `Hash`. This PR adds the
required trait implementations.

It's possible that the `Hash` implementations need to be improved; only
the `env_vars` field of `Evaluator` and the `thread_local` field of
`MemoryData` are actually being hashed. Omitting fields from a `Hash`
implementation is not incorrect, but could lead to collisions if the
ignored fields are changing constantly. Perhaps I should instead derive
`Hash` on a few more fields related to MIR validation?

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.

b233ada529 Change Option<Value> to Value, using ByVal(Undef). 
This job isn't quite finished because it caused me to discover bugs
related to reading `ByVal(Undef)` when a `ByValPair` is expected, e.g.
for a fat pointer. This wasn't a problem with the `None` of
`Option<Value>`, but I realized an equivalent bug existed even then,
since you could transmute a `u64` like `ByVal(Bytes(42))` to a fat
pointer type on 32-bit targets.

Likewise, you could transmute a fat pointer to `u64` and get panics
related to expecting `ByVal` but finding `ByValPair`, so the problem
goes both ways.

b36a83171b Turn PrimVal into an enum including Undefined. 
This is step 1 of a refactoring to fix #95. The `Undefined` variant is
so far unused and the old `bits` and `relocation` fields are emulated
with two new temporary methods. There should be no functional change due
to this commit.
