Ok, I have now implemented a set of flags in TSymtable of which one is 
set when the (global-,static-)symtable contains a class helper (I 
haven't refactored b_needs_init_final yet).

Here are the new results with the search for class helpers enabled (only 
two runs this time):

Run 1:
real	2m22.980s
user	0m47.140s
sys	0m4.333s

Run 2:
real	2m15.362s
user	0m47.274s
sys	0m4.140s
