1bfa7174 - [SPARC] Add TTI implementation for getPopcntSupport (#178843)

[SPARC] Add TTI implementation for getPopcntSupport (#178843) This is to inform the middle-end transform passes about the capabilities of the codegen backend. This should solve the issue where popcount loops not gets converted properly to `popc`, even if it's available (https://github.com/llvm/llvm-project/issues/171969).
