+ 7.8.02 Goetz
+ Implemented scc algorithm. Added datastructure to mark
+ backedges (ana/backedge.h) and to represent loops
+ (ana/irloop.h). The scc algorithm (ana/irscc.c) builds
+ both datastructures.
+ The algorithm does not yet work properly for interprocedural
+ graphs. Finds more loops than only recursions.
+
+ Improved place_code: now moves nodes out of loops.
+ Fixed bug in iropt.c: wrong parameter in debug info: iropt_dbg.c
+ Now flag set_opt_control_flow can be set to 1 again.

+ Added several constructors to tv.
+ Changed xgprintf so that full precision of double tvs is printed.
+ Fixed bug in irouts.c.
+
+ 22.4.2002 Goetz
