[CSKY] Fix the btsti16 instruction missing in generic processor

Normally, generic processor does not have any SubtargetFeature. And it
can just generate most basic instructions which have no Predicates to
guard.

But it needs to enbale predicate for the btsti16 instruction as one of the most basic instructions.
Or the generic processor can't finish codegen process. So Add FeatureBTST16 SubtargetFeature to generic ProcessorModel.

[CSKY] Add atomic expand pass to support atomic operation with libcall

For now, just support atomic operations by libcall. Further, should investigate atomic
implementation in CSKY target and codegen with atomic and fence related instructions.
