Description
-------

kjs: Fix shift/reduce issues in grammar.y + cleanup

The IterationStatement caused 1 shift/reduce conflict.
This is because of those 2 lines

DO Statement WHILE '(' Expr ')' ';' { $$ = new DoWhileNode($2, $5); DBG($$, @1, @3);}
DO Statement WHILE '(' Expr ')' { $$ = new DoWhileNode($2, $5); DBG($$, @1, @3); }

they only differ in ';', which bison/grammar.y has as default. So these 2 lines are basically the same
for bison, and it does not know know which one to pick. The Solution is easy, just removing
the ';' line will fix it.


The other changes fix bison warnings like

grammar.y:257.67: warning: a `;' might be needed at the end of action code
grammar.y:257.67: warning: future versions of Bison will not add the `;'

adding a simple ; is a simple fix and doesn't hurt


Diffs (updated)
-----

  kjs/grammar.cpp 71245a4 
  kjs/grammar.y d5e835f

Testing
-------

run ecmascript with and without this patch, same result, so it shouldn't introduce a regression.


Thanks,

Bernd Buschinski
