[PATCH] D57450: [RISCV] Set MaxAtomicInlineWidth and MaxAtomicPromoteWidth for RV32/RV64 targets with atomics

Looks sensible to me.

I'm just curious why we want to prevent emission of atomic LLVM instructions at this point. Won't LLVM's AtomicExpand perform a similar lowering already? Perhaps the goal is to save that pass some work?
