fa2064ae3b Fix problem with OptPtrLoad1 - never insert before the deleted code, always 
delete after! Otherwise labels will get wrong.

18d865e609 Fixed another problem with OptStackOps: Load tracking will not work across 
branches - if we find a label, just forget all information we had before.

f6c589bf8e Fixed problems with OptPrecalc. It removed insns because it results were known 
- but the insns generate a carry which may be needed later.
