846 or1200: Fix for cache bug related to first_{hit|miss}_ack

Under certain circumstances, when first_hit_ack and
first_miss_ack is asserted at the same time, cache data
would wrongly be overwritten with bus data.

845 or1200: l.lws support

Using the l.lws instruction doesn't work currently.
It simply skips the instruction. No exception or reaction.
The patch attached simply duplicates the behaviour of
l.lwz for l.lws.

815 OR1200 debug unit: prevent deadlock when trap instruction stalls

As per mailing list post <20120925160925.5725e06f@latmask.vernier.se>,
the debug unit could deadlock with the instruction decoder if the trap
instruction is held back by a pipeline stall. This change prevents that.

The problem can be reproduced by placing a breakpoint at an unfavorable
position with instruction cache enabled. In our test, this occurred
with or1200-cbasic when placing a breakpoint at test_bss using gdb, but
this is dependent on such factors as cache parameters and compilation
result.
