Jeff Epler dddd25a776 Combine similar strings to reduce size of translations 
This is a slight trade-off with code size, in places where a "_varg"
mp_raise variant is now used.  The net savings on trinket_m0 is
just 32 bytes.

It also means that the translation will include the original English
text, and cannot be translated.  These are usually names of Python
types such as int, set, or dict or special values such as "inf" or
"Nan".
