You can use default params here:

bool allow_escapes = true

     if (is_literal_one_byte() &&
         literal_length() == length &&
-        !literal_contains_escapes()) {
+          (allow_escapes || !literal_contains_escapes())) {
       const char* token =
           reinterpret_cast<const char*>(literal_one_byte_string().start());
       return !strncmp(token, data, length);
     }
     return false;
   }

+  }
+
+  inline bool LiteralMatches(const char* data, int length) {

Then this can be removed

+    return LiteralMatches(data, length, true);
+  }
+
   void IsGetOrSet(bool* is_get, bool* is_set) {
     if (is_literal_one_byte() &&
         literal_length() == 3 &&
