Andy McFadden 61914c8f79 Progress toward 64tass expression support
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.
