	* elaborate.h (systemtap_session): Add more command-line arguments.
	* staptree.h (verbose): Bad global, no donut.
	* elaborate.cxx: Temporarily disable verbose variable access.
	* main.cxx: Support more arguments, build/run passes.  Revamp
	temporary file generation and partial-pass output generation.
	* tapsets.cxx, translate.cxx: Emit just enough extra punctuation
	and fluff to make generated probe pass -Werror.
	* buildrun.cxx, buildrun.h: New files for passes 4/5.  Partial
	support for build pass, nothing on probe execution yet.
	* testsuite/transok/*.stp: Force just -p3, now that -p4/5 exist.
	* Makefile.am, Makefile.in: Corresponding changes.
