69439067 - [RISCV][GISel] Share an atomic load isel pattern GISel RV64 and SDAG RV32. NFC (#161721)

[RISCV][GISel] Share an atomic load isel pattern GISel RV64 and SDAG RV32. NFC (#161721) Use stricter type for RV64 only patterns. Stores are different because atomic_store doesn't differentiate truncating and non-truncating stores.
