	PR 2060 etc.
	* tapsets.cxx (visit_target_symbol): Tolerate failed resolution by
	letting target_symbol instance pass through to optimizer and
	type checker.
	* elaborate.cxx (semantic_pass_optimize): New family of functions and
	associated visitor classes.
	(visit_for_loop): Tolerate absent init/incr clauses.
	(semantic_pass): Invoke unless unoptimized (-u) option given.
	* main.cxx, session.h: Add support for flag.
	* staptree.cxx (visit_for_loop): Tolerate absent init/incr clauses.
	(traversing_visitor::visit_arrayindex): Visit the index expressions.
	(functioncall_traversing_visitor): New class.
	(varuse_tracking_visitor): New class.
	* staptree.h: Corresponding changes.
	* parse.cxx (parse_for_loop): Represent absent init/incr expressions
	with null statement pointer instead of optimized-out dummy numbers.
	* stap.1.in: Document optimization.
	* testsuite/{semko,transko}/*.stp: Added "-u" or other code to many
	tests to check bad code without optimizer elision.
	* testsuite/semok/optimize.stp: New test.

	* elaborate.cxx (unresolved, invalid, mismatch): Standardize error
	message wording.
	* stapfuncs.5.in: Tweak print/printf docs.
	* tapset/logging.stp: Remove redundant "print" auxiliary function,
	since it's a translator built-in.
	* testsuite/transok/five.stp: Extend test.
	* translate.cxx (emit_symbol_data): Put symbol table into a separate
	temporary header file, to make "-p3" output easier on the eyes.
	* buildrun.cxx (compile_pass): Eliminate test-mode support throughout.
	* main.cxx, session.h, translate.cxx: Ditto.
	* main.cxx (main): For last-pass=2 runs, print post-optimization ASTs.
