From: Robin Getz <robin.getz@analog.com>
Support a few more ASTAT bits with the standard insns that operate on
ASTAT bits directly.

opcodes/:
2010-09-21 Robin Getz <robin.getz@analog.com>
* bfin-dis.c (machine_registers): Add AC0_COPY, V_COPY, and RND_MOD.
(reg_names): Likewise.
(decode_statbits): Likewise; while reformatting to make manageable.
gas/:
2010-09-21 Robin Getz <robin.getz@analog.com>
* config/bfin-defs.h (statusflags): Add AC0_COPY, V_COPY, and RND_MOD.
* config/bfin-lex.l: Tokenize AC0_COPY, V_COPY, and RND_MOD.
