Ilya Leoshkevich f689befde6 target/xtensa: Make sure that tb->size != 0 
tb_gen_code() assumes that tb->size must never be zero, otherwise it
may produce spurious exceptions. For xtensa this may happen when
decoding an unknown instruction, when handling a write into the
CCOUNT or CCOMPARE special register and when single-stepping the first
instruction of an exception handler.

Fix by pretending that the size of the respective translation block is
1 in all these cases.
