* fixed a potential bug in destroyregs regarding the removal of
...
unused loads
* added destroyDependingRegs() procedure and use it for the fix in
the previous commit (safer/more complete than what was done before)

* fixed bug where the contents of a register would not be destroyed
...
if another register on which these contents depend is modified
(not really merged, but same idea as fix in fixes branch,
LAST_MERGE tag is updated)

* 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)

* fixed a serious bug in the CSE which (I think) only showed with
...
-dnewoptimizations when using multi-dimensional arrays with
elements of a size different from 1, 2 or 4 (especially strings).
* made the DFA/CSE more robust (much less dependent on specifics of the
code generator)

"mov reg, ref"
