A large portion of the VTK-m filters are now compiled into the vtkm_filter library. These pre-built filters now don't include the respective hxx file to remove the amount of template instantiation users do. To verify that this removal reduces compiler memory ( and maybe time) I profiled the compiler while it building filter tests in debug mode. Here is a selection of results: ``` CleanGrid 10.25s => 9.01s, 901MB => 795MB ExternalFaces 13.40s => 5.96s, 1122MB => 744MB ExtractStructured 4.69s => 4.75s, 492MB => 492MB GradientExplicit 22.97s => 5.88s, 1296MB => 740MB ```
