fixed CRLF

fixed CRLF

 - cached liveness information now for any node BEFORE patching the graph:
   this fixes the problem that the liveness is wrong after predecessors
   of Phi nodes are patched tp fxch and fpush and should speed up the
   simulator because the complexity lowers from O(n^2) to O(n)
 - fixed wrong cases for reverse operations ... again

 - fixed debug output for x87 floating point nodes (uncritical)

fixed debugging in list scheduler

 - removed the kludge double push hack
 - some minor bugs fixed

create all convs, remember those to be killed and kill them after transformation (to preserve modes during transformation)

- Stackparams get rematerialized now
- several warning fixes

while limiting registers: clear ignore registers before applying limits from config, otherwise esp is always cleared

 - do not delete the graph before it is access the last time ...
