* daopt386: changes to getnextinstruction/getlastinstruction so they
...
ignore labels who have is_addr set
+ daopt386/csopt386: remove loads of registers which are overwritten
before their contents are used (especially usefull for removing superfluous
maybe_loadesi outputs and push/pops transformed by below optimization
+ popt386: transform pop/pop/pop/.../push/push/push to sequences of
'movl x(%esp),%reg' (only active when compiling a go32v2 compiler
currently because I don't know whether it's safe to do this under Win32/
Linux (because of problems we had when using esp as frame pointer on
those os'es)
