 I've improved error reporting when this kind of thing happens

   * Refactor, and improve error messages (cf Trac #3395)
   Ignore-this: e7205f5bcf8408ff791ba19156e48461

   The Convert stuff should not panic if the programmer hands over an
   invalid TH term; instead it should give a graceful error message.
   Largely this had been done, but not for do-blocks, so this patch
   fixes that problem.

   Moreover, I did some refactoring and tidying up, which is why
   so many lines of code have changed


     M ./compiler/hsSyn/Convert.lhs -153 +146
