assembly as this is not the desired behaviour for end-users. Small change to a unit test to implement this without requiring the inline assembly.

Revert "[Sparc][Leon] Missed resetting option flags from check-in 278489."
Revert "[Sparc][Leon] Errata fixes for various errata in different
versions of the Leon variants of the Sparc 32 bit processor."
This reverts commit r274856, r278489, and r278492.

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.
These changes update older versions of these errata fixes with improvements to code and unit tests.

Passes to fix three hardware errata that appear on some LEON processor variants.
The instructions FSMULD, FMULS and FDIVS do not work as expected on some LEON processors. This change allows those instructions to be substituted for alternatives instruction sequences that are known to work.
These passes only run when selected individually, or as part of a processor defintion. They are not included in general SPARC processor compilations for non-LEON processors or for those LEON processors that do not have these hardware errata.
