* config/tc-m68k.c (init_table): Now const. Always include 68851

* config/tc-m68k.c (init_table): Now const.  Always include 68851
data, so that "bc" is available to 68040 cache instructions.  Added
"tt0", "tt1", and 68ec030 variants.
(md_assemble): Complain if 68000 (only) and 68881 are specified.
(enum _register): Added TT0, TT1.
(m68k_ip, cases '3' and 't'): Handle new operand type codes.  Pass
line number correctly in "internal error" messages.  Don't print
architecture-mismatch message for operand errors.

From Colin Smith (colin@wrs.com):
* config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather than
install_operand.
