Summary:
* Add LLVM_ATTRIBUTE_UNUSED_RESULT used to slicing methods in order to
emphasize that the slicing is not done in place.
* Change device memory slice function name from `drop_front` to `slice`
in order to match the naming convention of `llvm::ArrayRef` and host
memory slice.
* Change the parameter names of host memory slice functions to
`DropCount` and `TakeCount` to match device memory slice declarations.

Summary:
Improve the error-prone interface that allows users to pass host
pointers that haven't been registered to asynchronous copy methods. In
CUDA, this is an extremely easy error to make, and instead of failing at
runtime, it succeeds and gives the right answers by turning the async
copy into a sync copy. So, you silently get a huge performance
degradation if you misuse the old interface. This new interface should
prevent that.

Summary:
With these changes, we can put parallel-libs within llvm/projects and
build as normal.
This is kind of the minimal change I could figure out how to make while
still making us compatible with llvm's build system. Some things I'm
not thrilled about include:
* The creation of a CoreTests directory (the macros really seemed to
want this)
* Pulling SimpleHostPlatformDevice.h into CoreTests. It seems to me
this should live inside unittests/include, or maybe tests/include,
but I didn't want to make that change in this patch.
One important piece of work that remains to be done is to make
$ ninja check-streamexecutor
run all the tests. Right now the only way I've figured out to run the
tests is
$ ninja projects/parallel-libs/streamexecutor/unittests/StreamExecutorUnitTests
$ projects/parallel-libs/streamexecutor/unittests/CoreTests/CoreTests
