Updating MultiBlock to use `diy` for computing block summaries like
ranges, bounds etc. This makes it possible to MultiBlock to
work in distributed operations without explicit logic.
Previously we allowed a const ref as we would make a copy, this only works
as it relies on RuntimeDeviceTracker implementing state through a shared_ptr.
Instead if we require modifiable types only we can make TryExecute more
efficient and clearer on what it does.
By using perfect forwarding we can reduce not only the amount of TryExecute
signatures, but we can enable the ability to pass temporary functors to
TryExecute.
At the same time we have optimized TryExecute by moving the string generation
code into a single function that is compiled into the vtkm_cont library.
The end result is that the vtkm_rendering library size has been reduced from
12MB to 11MB, and we shave off about 5% of our build time.
The implementation of ScanExclusiveByKey in
DeviceAdapterAlgorithmGeneral by shifting values in the input values
array and then calling ScanInclusiveByKey. However, the temporary
shifted values array was created using the key type instead of the
values type. This caused a compile error when the keys and values had
different types.
For std::copy to optimize a copy to memcpy, the valuetype must be both
trivially constructable and trivially copyable.
The new copy benchmarks highlighted an issue that std::copy'ing pairs
and vecs were not optimized to memcpy. For a 256 MiB buffer on my
laptop w/ GCC, the serial copy speeds were:
UInt8: 10.10 GiB/s
Vec<UInt8, 2> 3.12 GiB/s
Pair<UInt32, Float32> 6.92 GiB/s
After this patch, the optimization occurs and a bitwise copy occurs:
UInt8: 10.12 GiB/s
Vec<UInt8, 2> 9.66 GiB/s
Pair<UInt32, Float32> 9.88 GiB/s
Check were also added to the Vec and Pair unit tests to ensure that
this classes continue to be trivial.
The ArrayHandleSwizzle test was refactored a bit to eliminate a new
'possibly uninitialized memory' warning introduced with the default
Vec ctors.
In generic code, it's a pain to use the equality operators since they
requires the ValueType and Storage to match, else the operator is undefined.
This commit adds operators for such comparisons, as well as a unit test.

The idea of the test was to turn off the "default" storage to ensure
that the fancy array was not making assumptions about the storage of its
delegate array. But there is lots of code elsewhere that uses the
default storage (rightly so) to create intermediate arrays, which will
fail if you disable the default storage. This was causing a test to
fail, so turn default storage back on for this case.
This is a convenience method to do a deep copy of an array. This comes
up a lot, but can be a pain if you don't have a specific device adapter
on which to do the copy.

Previously, ConvertNumComponentsToOffsets always used TryCompile on the
global set of runtime devices. That is still the default behavior, but
now you are able to specify your own runtime tracker. Also, there are
now versions of ConvertNumComponentsToOffsets that take a device adapter
tag.
Previously once an ArrayHandle was stolen it was placed in an invalid state
where it could not used again by VTK-m. Now instead after being stolen it
is placed into a state where it is identical to memory allocated outside
of VTK-m and passed in.

The external faces filter and worklet now pass input

Added tests to the external faces filter and worklet.
This is part of #43, which will ultimately simplify the
ArrayHandleCompositeVector to a new implementation that can be easily
written to. Part of this effort will remove the ability to pull a single
component from a vector-typed input ArrayHandle for use in the
CompositeVector, and this new class makes sure we can still support that
usecase.
The old templated array transfer mechanism generated a lot of code
that ended up doing a simple, type-agnostic memcpy for most devices.
This patch specialized array handles for basic storage and uses a
fast-path array transfer implementation. This reduces the size of the
vtkm_cont library by 27% on gcc (from 6.2MB to 4.5MB).

windows.h was only being included for MSVC, while in UnitTestTimer.cxx, the
Windows function Sleep was being called after check for _WIN32. This was
causing compilation failure in MINGW.
Fixes#122
Following what was done with ArrayRangeCompute, the GetRange and
GetBounds methods are embedded into the vtkm_cont library for the most
common type lists.
Also, and probably more importantly, the device adapter is no longer one
of the arguments for either of these methods. It is no longer needed as
ArrayRangeCompute no longer needs it.
Most uses of ArrayRangeCompute just want to get the range of the data
and probably don't have a particular device in mind. Thus, it is better
to use a TryExecute internally use whatever devices are available.
Note that when using TryExecute, the calling code is expected to be able
to support all devices. That might not always be the case. Thus, I am
experimenting a bit with how we incorporate this in a library. The
advantage of having the code compiled in a library is that you only have
to compile it once and the calling code does not need to worry about
CUDA, etc.
However, because ArrayRangeCompute is templated, we can only pre-compile
some subset of array handle types. The most common are compiled into the
code (matching all the predefined ArrayHandles as well as some special
cases). If the code wants to use some other type, it has to include
ArrayRangeCompute.hxx. The only place where this is necessary is a test
that intentially trys to find the range on an uncommon type.
If array portals were to support virtual methods, then we should be able
to modify this code so that we could precompile for all array handle
types.
There were some issues for device adapter algorithms (like scan and
reduce) for empty arrays or arrays of size 1. This adds tests for these
short arrays to the device adapter algorithm tests and fixes these
problems.

It was a typedef for a Portal. Instead of setting the portal directly,
the portal is just sent to a function, so we don't directly use this
type anymore.
Not a big deal, but it could cause compiler warnings.
This makes it easier to see what is going on in the fancy arrays and do
diagnostics.
This change required some changes to printSummary_ArrayHandle to support
more array types.
Previously if you constructed an array handle without allocating it, you
would get an error if you tried to use the array as input. This
conflicted with some recent changes to accept empty vectors.
Now when you try to use an unallocated ArrayHandle as input (calling
PrepareForInput or PrepareForInPlace), it internally calls Allocate(0)
(to establish internal state) and sets up a valid execution ArrayPortal
of size 0.
