  Working on merge: changed the way that we handle kernels in the AST and SimpleAST IRs (treat
  them like literals, instead of like variables).  Added code to rewrite Inside tests in Simple
  IR to use the image instead of the field, which fixes a problem with trying to do inside tests
  on Ein fields.  Added code to promote locals to globals as part of the simplify-vars phase.
