We exposed `Core.IntLiteral()`, `Core.FloatLiteral()`, `Core.CharLiteral()`, and `Core.Bool()` as functions as a workaround, because we had no way to provide the type names without parentheses that the design requests. But now we can do so, by using an alias. Switch all of these over from being functions to simply being names of the corresponding types. Assisted-by: Gemini via Antigravity
