- Removing test exclusions since they seem to be passing
- Adding macros for PowerPC to exclude poor FMA tests
(`vtkm::DiffernceOfProducts` on Power 9 using FMA produces the same result as
`a*b - c*d`, when ideally it's expected to produce a more accurate result)
Now that it is easier to select which unit tests should be compiled by a
device compiler (and run on a device), allow the transport classes to be
tested on actual devices rather than just the serial device.
Previously, each device adapter implementation had their own version of
this test by including a common header. Simplify this by making a single
test in UnitTests_vtkm_cont_testing, which can now be compiled for and
tested on a device.

This header file contained tests for a bunch of fancy array handles so
that they could be compiled for each device. These tests were bunched
together because they were replicated for each device implementation,
which was a hassle. However, having a bunch of tests crammed together is
problematic for a number of reasons.
The new testing no longer has a need to make a separate test for each
device. Thus, the tests for the individual devices are removed, and the
tests are split up and added to the basic vtkm_cont tests. In some
cases, individual tests already existed there as well (probably because
the developer did not see the test).

We have been noticing occasional failures of UnitTestTimer on the
dashboard for CUDA devices. The timer seems to be recording less time
than is actually elapsed.
The problem might be that the CUDA timer actually inserts fences to the
CUDA stream rather than record the current time. Thus, the actual time
might start after some pending operations complete.
To attempt to match the UnitTestTimer measurements closer to wall-clock
time, add a synchronize before starting the timer.

f598656d5 Enable reallocation of ArrayHandleBasic with moved std::vector

Previously, the number of buffers held by an `ArrayHandle` had to be
determined statically at compile time by the storage. Most of the time
this is fine. However, there are some exceptions where the number of
buffers need to be selected at runtime. For example, the
`ArrayHandleRecombineVec` does not specify the number of components it
uses, and it needed a hack where it stored buffers in the metadata of
another buffer, which is bad.
This change allows the number of buffers to vary at runtime (at least at
construction). The buffers were already managed in a `std::vector`. It
now no longer forces the vector to be a specific size.
`GetNumberOfBuffers` was removed from the `Storage`. Instead, if the
number of buffers was not specified at construction, an allocation of
size 0 is done to create default buffers.
The biggest change is to the interface of the storage object methods,
which now take `std::vector` instead of pointers to `Buffer` objects.
This adds a little hastle in having to copy subsets of this `vector`
when a storage object has multiple sub-arrays. But it does simplify some
of the templating.
It is possible to create an `ArrayHandleBasic` from a `std::vector`. It
is possible to move the `vector` into the `ArrayHandle` such that the
`ArrayHandle` takes over the memory. When you do this, the `ArrayHandle`
should be able to resize the data if necessary. However, this was not
working.
There were actually 3 problems that were colluding to lead to this
incorrect behavior.
1. The `Buffer` object was not allowing the reallocation of pinned data.
Pinned data means that the `Buffer`'s memory is pointing to some user
data that should stay where it is. Instead, the `Buffer` should attempt
to reallocate the pinned data using its registered realloc method. This
registered realloc method should be the think to throw the exception if
reallocation is not supported. (Technically, the memory doesn't really
need to be pinned since the data is moved and the user no longer has
direct access to it. But for implementation reasons, moved `vector` data
is pinned.)
2. The `InvalidRealloc` function was not properly throwing an exception.
This was not noticed since `Buffer` was inappropriately throwing an
exception for it.
3. The reallocation method `StdVectorReallocater` had a bad assert that
crashed the program during reallocation.
nvcc is giving me lots of annoying warnings about unused functions.
Typically, this warning is given when a function declared as static or
in an anonymous namespace is never used. The "functions" in question are
not really functions. They are templated methods (in a class in an
anonymous namespace).
Specificaly, I'm getting errors like this:
```
/.../vtkm/cont/testing/UnitTestArrayHandleDecorator.cxx(96): warning #177-D: function "<unnamed>::DecoratorTests::InvertibleDecorImpl::CreateFunctor(PortalTs&&...) const [with PortalTs=<vtkm::cont::internal::decor::GetWritePortalType<vtkm::cont::ArrayHandleCounting<signed char>>, vtkm::cont::internal::decor::GetWritePortalType<vtkm::cont::ArrayHandleConstant<signed char>>, vtkm::cont::internal::decor::GetWritePortalType<vtkm::cont::ArrayHandle<vtkm::Int8, vtkm::cont::StorageTagBasic>>>]" was declared but never referenced
```
That said, these warnings appear to be an annoying but harmless bug in
nvcc. This warning is in error because
1. The method in question is _definitely_ being used.
2. I'm pretty sure this warning should not be given for a templated
method even if it was never used. SFINAE alone should be enough
justification to allow this to exist without warning.
The easiest way around the spurious error is to declare these structures
in a namespace with a name.
The `vtkm_unit_tests` function in the CMake build now allows you to specify
which files need to be compiled with a device compiler using the
`DEVICE_SOURCES` argument. Previously, the only way to specify that unit
tests needed to be compiled with a device compiler was to use the
`ALL_BACKENDS` argument, which would automatically compile everything with
the device compiler as well as test the code on all backends.
`ALL_BACKENDS` is still supported, but it no longer changes the sources to
be compiled with the device compiler.
The `UnitTestAlgorithm` test was running several device algorithms, but
it was not checking the results of any of them. (In fact, it was not
even setting values in the input arrays.) So, it verified that the
execution did not crash, but did not verify correctness.
Add checks to the results to make sure this executed correctly. (Part of
the reason for this change was a warning that popped up because a result
value was never used.)
