microblaze: Fix -Os right shift optimization is allowed into delay slot

alpsayin · alpsayin · commit 81825cc5d8d6 · 2024-10-18T17:29:32.000+01:00
In picolibc testing it's found that this produces code that compiler
squeezes into a single delay slot. And thus only the first instruction
emitted by this optimization is run and the rest is skipped.
