	* TODO: Removed entries already represented in bugzilla.
	* elaborate.cxx: Rewrite type inference for several operators.
	* main.cxx (main): For -p2 runs, print types of function/probe locals.
	* parse.cxx (scan): Identify more two-character operators.
	(parse_comparison): Support the whole suite.
	* translate.cxx (visit_unary_expression, logical_or_expr,
	logical_and_expr, comparison,ternary_expression): New support.
	* testsuite/parseok/semok.stp: Clever new test.
	* testsuite/transok/four.stp: New test.
	* testsuite/*: Some tweaked tests for syntax changes.
