fix 6502 code gen errors for the address-of (assignAddressOfIndexedPointer)
fix 6502 code gen errors that make some of the pointer examples crash. Important to do this before building more on wrong code!

fix compiler crash (virtual) for ^^List @shared lp ; ^^List @shared temp = lp[2]
fix invalid pointer arithmetic in 6502 code for &&lp[2] (it adds 2 to the pointer itself rather than the value of the pointer, and 2 is wrong as well)
