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.

We now lock at the "leaves" on the types, rather than locking at references.

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.
