ccdef was broken by the following commit:
commit 7d748dc6e2
Author: ggn <ggn@atari.org>

Fix for #159: Split register sets according to architecture into
different tables so they don't clash with label/symbol names.
Modified tokeniser to use different tables when scanning for
registers
This change fixes it by moving the ccdef and .ccdef
tokens from the unary table to the keyword table.
There's still a ways to go before this will work properly as we need to
add proper fixup handling and origin (".org") bookkeeping. As it is now,
the addition of all the miscellaneous bits and bobs to support the main
56K assembler are in place but they don't cause any regressions to the
existing assemblers already present in RMAC. Stay tuned for Round 2!
