  Log Message:
  -----------
  Reapply "[RISCV] Remove experimental from Ztso. (#96465)"

This was reverted in f985a8826bfa4ca3d23e654185de35e30ea6dc79.  Since that,
the default WMO lowering has moved to A67 compatible, the ABI attribute
emission has landed (off by default), and the LLD change to merge said
attributes have landed.  Our ztso lowering is believed to also be A67
compatible, and no known issues remain.

Original commit message:

Ztso 1.0 was ratified in January 2023.
