The BYTEOP2M insn was part of the initial Blackfin designs, but never made
it into any actual silicon. So punt support for it.

Currently, trying to declare single letter variables in Blackfin assembly
can sometimes lead to parser errors if that letter is used for insn flags.
For example, X, Z, S, M, and T are used to change the behavior of insns:
R0 = 1; R0 = 1 (X); R0 = 1 (Z);
But the current parser just looks for single letter tokens rather than
ones that show up in the (FLAGS) field. So only match these letters as
flags when they're in parentheses.
Not a complete fix, but it at least lets gcc tests pass now (the test
gcc/testsuite/gcc.c-torture/compile/mangle-1.c to be exact). A complete
fix would require a significant parser rewrite in order to handle:
R0 = (x) (x); /* zero extend the address of the symbol "x" */
R0 = W; R0 = W[P0];

Accept any 8bit char with the high bit set so as to support multibyte
characters. Also use the locale safe regular expressions to match
chars/digits. This brings the Blackfin assembler inline with the
behavior of other assemblers.

Support a few more ASTAT bits with the standard insns that operate on
ASTAT bits directly.

There is a pseudo debug insn named ABORT that is commonly used in
simulation, so support it in the assembler too. The disassembler
already supports it.
