The older Xcode 9 compiler has troubles with ArrayHandleDecorator that
are similar to those of earlier Microsoft and Cuda compilers.
Note that the logic behind the changed compiler check has a lot of
guesswork involved. I noticed this problem on a laptop with Xcode 9
installed. However, even though Xcode uses the clang compiler, it
notoriously does not return the actual clang version. Instead, it
returns some toolchain version that has nothing to do with it. I'm
pretty sure Xcode 9 is using clang version 4 under the covers, but
__clang_major__ reports 9. Oddly, Xcode 10 reports __clang_major__ as 8,
so that's not too much help. So instead, we check for
__apple_build_version__, which returns the Xcode version (sort of) and
that seems a reasonable comparison.
Although I have not tried it, I'm willing to bet that the older clang
outside of Xcode will also have issues. Here is where the real guesswork
takes place since I don't have handy compilers to try. Like I said, I
think the internet claims that Xcode 9 is using clang 4, so also add to
the check any compiler that reports itself clang 4 or below.
The previous implementation of `RuntimeDeviceTracker` occasionally
outputted a log at level `Info` about devices being enabled or disabled.
The problem was that the information given was inconsistent (so it would
sometimes announce one change but not announce a different corrective
change). This could cause weird confusions. For example, when you used a
`ColorTable`, it would use a `ScopedRuntimeDeviceTracker` to temporarily
force the device to `Serial`. The log will just tell you that the device
was forced to `Serial` but never tell you that the devices where
restored to include actual parallel devices.
This change helps correct these with the following changes:
* Added a new log level, `DevicesEnabled`, that is a higher level than
`Info`. All logging from `RuntimeDeviceTracker` goes to this log
level.
* Change the logging output of `RuntimeDeviceTracker` to output a list
of currently enabled devices whenever a change happens. That way you
don't have to guess what happend for each change.
* Change `ScopedRuntimeDeviceTracker` to log whenever the scope is
entered or left.
The tao ones won't compile otherwise. This should be okay, since these
are all just compile time helpers on host-only functions -- they won't
generate different sized data structures etc if we mix them in the
same build.

VTK-m now provides the following filters with the default policy
as part of the vtkm_filter library:
- CellAverage
- CleanGrid
- ClipWithField
- ClipWithImplicitFunction
- Contour
- ExternalFaces
- ExtractStructured
- PointAverage
- Threshold
- VectorMagnitude
By building these as a library we hope to provide faster compile
times for consumers of VTK-m when using common configurations.

This patch removes (or conditionally removes) the Set method from
portals that are read-only so that IsWritableArrayHandle will work as
expected. The ArrayPortal doxygen has been updated to reflect this.
The remaining exceptions are `ArrayPortalVirtual` and
`ArrayPortalMultiplexer`, since their mutability cannot be determined at
compile time.
