Daniel Cederman a96bcd088d Revert "This pass, fixing an erratum in some LEON 2 processors..." ...

Summary:
Reading Atmel's AT697E errata document this does not seem like a valid
workaround. While the text only mentions SDIV, it says that the ICC flags
can be wrong, and those are only generated by SDIVcc. Verification on
hardware shows that simply replacing SDIV with SDIVcc does not avoid
the bug with negative operands.

This reverts r283727.
