refactor position tracking in the parser
This change replaces direct source line and column tracking in the
tree_* classes with the beginning and ending positions in tokens
created by the lexer. All line and column arguments for tree_*
constructors have been removed. More tree_* classes have been
modified to store tokens that are part of the syntax but not necessary
for evaluation.
