- BugFix: the mode of a Load must be its load_mode, else a Byte load would be congruent a float load (which is true to some extend but not we want to handle here)
- BugFix: two Blocks are never congruent: this cannot be detected by combo either and fixed the IJmp predecessor problem of combo_load_mode.c

some adjustment to float convs (skip some strictconvs when no_fold_const is not set, but always strict conv in int->float converstion)

introduce fp_no_float_fold flag for frontends which do not query the backends float arithmetic mode yet
