Make the dcache (code/stack cache) handle line reading errors better
The dcache (code/stack cache) is supposed to be transparent, but it's
actually not in one case. dcache tries to read chunks (cache lines)
at a time off of the target. This may end up trying to read
unaccessible or unavailable memory. Currently the caller gets an xfer
error in this case. But if the specific bits of memory the caller
actually wanted are available and accessible, then the caller should
get the memory it wanted, not an error.

* dcache.c (dcache_read_memory_partial): If reading the cache line
fails, fallback to reading just the memory the caller wanted.
