  [CAF] Adds basic support for a set of coarray collectives
  
  This adds some basic support for a set of coarray collectives that have been
  proposed for inclusion into the Fortran standard:
  
  co_sum, co_product, co_maxval, co_minval
  
  Front-end support also was added for:
  
  co_all, co_any, co_count, co_findloc, co_maxloc, co_inloc
  
  A few general CAF bug fixes are also in this commit:
  
  * In some cases the front-end would reuse a dope vector of a coarray type for a
  non-coarray variable, which confused the subsequent back-end lowering phase.
  This commit prevents such a thing from happening.
  
  * The compiler didn't handle coscalars as arguments in CAF intrinsic calls,
  specifically this_image, image_index, lcobound, and ucobound. This commit
  adds support for this in the front-end. It required generation of a dope
  vector for non-allocatable coscalars and some other changes.
  
  Also, there were some minor adjustments to the functions names that are
  created by the compiler for consistency.
