- with -mcpu=native for automatic detection and -armpl for linking in
  the performance libraries

STYLE: relocate -mcpu into compiler instead of compiler-flags (#1225)

pointNormals calculation gets triggered through processorfvPatches
so on processors that don't have these bypass this. This leads
to the global reduction hanging.

ENH: add -prefs option to pass in a preferences configuration file

- in addition to managing different vendors and versions, it may also
  be necessary or desirable to have a particular variant
  (eg, profiling, release, etc).

  Devise a new meaningful name for the variant and create a
  corresponding wmake rule.

  Eg, SYSTEMOPENMPI-profiling with a corresponding
      "wmake/rules/linux64Gcc/mplibSYSTEMOPENMPI-profiling" file
  that has suitable content for your system.

CONFIG: intel-mpi use intel64/ paths only for config and wmake rules (#1153)

- previously adjusted the config files, but missed the changes
  required for the wmake rules too.

  Now simply migrate to using  "intel64/{include,bin,lib}"
  instead of the older naming  "{include,bin,lib}64"

  These changes work since at least intel-mpi 2015 (5.x), but possibly
  earlier as well

- retrieved value for the modelType was masked by a local variable

- checkIn() was incorrectly conditional on the register state of the
  source object.

Partial patch from .org commit 6dc48b62d948

- was WM_PROJECT_API in the environment and FOAM_API in dictionaries.

  Make these both consistently FOAM_API.
  This is a non-breaking change, since the value of WM_PROJECT_API
  (added in 1812) and/or FOAM_API is purely informative.
  For the current correct values, always use

    * foamEtcFile -show-api
    * wmakeBuildInfo -show-api

- If using a non-clang compiler suite (gcc, intel, etc) the additional
  lbraries required for mesa with llvm pipelines may not be found.

  Provide a mesa_llvm configuration with in the 'vtk' config file.
  Can use the usual types of settings

     * mesa_llvm=llvm-4.0.1
     * mesa_llvm=none
     * mesa_llvm=system

- could be triggered if running in parallel, but requesting procIDs
  to be written with a non-parallel version of the writer.

- uses the value of foamVersion::api, which should be reliable.

- and support setting cmake_version within the paraview config files

- looks slightly messier without associative arrays, but improves
  portability. Should now also work with dash.

STYLE: support wmakeBuildInfo -cmp and -check options as equivalent
