Extract binary lvalue operators (#2630)

Browse Source 
This patch substitutes all binary lvalue operators with an assigment + the corresponding binary operator.
E.g. A += (expression) is pasred as A = A + (expression).

Due to this replacement, all the related binary lvalue CBC opcodes can be removed.
Also the arithmetic related VM instructions can put their result directly onto the stack, since no more checking is needed.
