    PR13155: separate compilation for tracepoint-related functions
    
    The linux kernel's tracepoint headers are sometimes mutually
    conflicting, defining structs etc. differently.  Since we need to use
    each header in its natural habitat, we need to separately-compile
    those tracepoint-related functions that absolutely need access to
    those declarations.  This is quite new to us as so far, the translator
    has usually emitted a single translated_source output, plus the
    stap-symbols.h file.
    
    * buildrun.cxx (compile_pass): Compile auxiliary sources into main module.
    * tapsets.cxx (tracepoint_derived_probe_group::emit_module_decls): Effectively
      rewrite to create per-tracepoint-header auxiliary source files.
    * session.cxx (op_create_auxiliary): New function.
    * translate.cxx (translator_output): Add filename field.
    * session.h, translate.h: Corresponding changes.
    * hash.cxx (find_script_hash): Rename primary source file to stap_XXX_src.c.
    * main.cxx (passes_0_4): Ditto.

    * buildrun.cxx (run_make_cmd): Do it here, to cover all make invocations,
      (make_tracequeries) ... instead of here.
