Test case
The simplest occurrence that I was able to produce is attached, but this can
also be produced by having a function that takes two 64 bit integers, converts
them to i129, multiplies them as i129 and then returns i64 truncated result.
The crash also occurs with larger integers, but everything seems to work well
for integers with less bits than 129.
How to reproduce: llc i129-crash.ll</pre>
