  Add a ShaderCompileTreeTest base class to use in compiler tests
  
  The test class provides facilities for parsing test shader source into
  an AST and determining compile status. Compilation flags change for
  some of the tests, but this should only have a minor effect on code
  coverage - mostly affecting non-core parts such as intermediate
  output.
