Gave cc65 its own expression generator, as the precedence table seems atypical if not unique. Configured 64tass to use the "simple" expression mode. Added some operations on a 32-bit constant to 2007-labels-and-symbols to exercise the current worst-case expression (shift + AND + add). Tweaked the Merlin expression generator to handle it. (issue #16)
