Cuong Manh Le fd208c8850 cmd/compile: remove constant arithmetic overflows during typecheck
Since go1.19, these errors are already reported by types2 for any user's
Go code. Compiler generated code, which looks like constant expression
should be evaluated as non-constant semantic, which allows overflows.

Fixes #58293
