The BYTEOP2M parser incorrectly calls BYTEOP2P to generate the opcode.
Once we've fixed that, it's easy to see that the disassembler also likes
to decode this insn incorrectly. So fix that and then add some tests.

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];
