cmd/compile: handle string concatenation in static init inliner Static init inliner is using typecheck.EvalConst to handle string concatenation expressions. But static init inliner may reveal constant expressions after substitution, and the compiler needs to evaluate those expressions in non-constant semantic. Using typecheck.EvalConst, which always evaluates expressions in constant semantic, is not the right choice. For safety, this CL fold the logic to handle string concatenation to static init inliner, so there won't be regression in handling constant expressions in non-constant semantic. And also, future CL can simplify typecheck.EvalConst logic.
