The CPU will freeze until power-off if a cached access is performed to a non RDRAM area. This obviously never happens with games, but it is a not so uncommon error when doing very low level development on the system.

This patch emulates the freeze for the data cache, and for the instruction cache when using the interpreter. Implementation for instruction cache and recompiler is left as a followup.
