src/compiler/types.ts

    TemplateLiteral = 1 << 27,  // Template literal type
    StringMapping   = 1 << 28,  // Uppercase/Lowercase type
+    /** @internal */
+    Reserved1       = 1 << 29,  // Used by union/intersection type construction


This is kind of funky - I'd just directly make this IncludesConstrainedTypeVariable.
