oth a1ba971cd8 [Interpreter] Enable assignments in expressions. 
This change introduces register re-mapping to avoid assignment hazards
in binary expressions. Expressions that cause problems typically have
the form y = x + (x = 4);. The problem occurs because the lhs value
evaluates to the register holding x. The rhs updates that register and
then applying the operation would use the new value as the lhs.

By tracking loads and stores in binary expressions the generator is now
able to detect when condition occurs and uses a temporary register for
the rhs value. When the binary expression evaluation is complete the
variable is updated with the latest temporary.

A new bytecode Mov performs this update without touching the
accumulator.
