Fixed bug. After I$ invalidated. If the pipelined wasn't stalled the I$ still output the old instruction on the next cycle. Now the I$ ensure that invalidation leads to the next cycle not hitting.

Fixes some but not all of the Issue #405 bugs. Fixes non-cached atomics, zifence when there is no dcache, and more serious bug with compressedF not supressed on the last cycle of a bus fetch.

THis includes fix for special case when conversion from fp to int/long. The previous src did not test both the flags and result and so missed this subtle bug when an Invalid happens for this type of conversion. These results are indications of undefined behavior for these operations. All fp operations now passs when this update is fixed. Much of the information why these outputs should occur is somewhat alluded to by Pascal Cuoq originally from INSA in Lyon here: https://frama-c.com/2013/10/09/Overflow-float-integer.html
