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.

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.
