* They didn't work before, because the location of the tests caused the
'sysroot' option to crate lookup to be wrong for finding the correct stage's
core/std libraries. This moves the compiled tests from the $host/test
directory into a $host/$stage/test directory. This means that the sysroot will
be correct and the core/std libraries can actually be found
* The LLVM bindings apparently aren't threadsafe, so we can't run multiple tests
in parallel.
This closes#5204 and #6421.
This also removes the `vecs_implicitly_copyable` lint (although now reading #6421, this may not be desired?). If we want to leave it in, it at least removes it from the compiler.
fail!() used to require owned strings but can handle static strings
now. Also, it can pass its arguments to fmt!() on its own, no need for
the caller to call fmt!() itself.

Also fix up all the fallout elsewhere throughout core. It's really nice being
able to have the prelude.
I'm not quite sure how resolution works with traits, but it seems to me like the public imports at the top-level of the core crate were leaking into the sub-crates, but that could also be working as intended. Regardless, things compile without the re-exports now.

* Move `SharedMutableState`, `LittleLock`, and `Exclusive` from `core::unstable` to `core::unstable::sync`
* Modernize the `SharedMutableState` interface with methods
* Rename `SharedMutableState` to `UnsafeAtomicRcBox` to match `RcBox`.
When trying to import nonexistent items from existing modules, specify that
that is what happened, rather than just reporting "unresolved name".
Ideally the error would be reported on the span of the import... but I do not see a way to get a span there. Help appreciated 😄
This pull request adds 4 atomic intrinsics to the compiler, in preparation for #5042.
* `atomic_load(src: &int) -> int` performs an atomic sequentially consistent load.
* `atomic_load_acq(src: &int) -> int` performs an atomic acquiring load.
* `atomic_store(dst: &mut int, val: int)` performs an atomic sequentially consistent store.
* `atomic_store_rel(dst: &mut int, val: int)` performs an atomic releasing store.

Every unresolved import is reported. An additional error message isn't useful
and obscures (imo) the real errors: I need to take it into account when
looking at the error count.
