Errata fixes for various errata in different versions of the Leon variants of the Sparc 32 bit processor.

The nature of the errata are listed in the comments preceding the errata fix passes. Relevant unit tests are implemented for each of these.

Note, I won't be able to see any response comments until after 30th August 2016, so please don't expect any immediate responses.
