llvm/test/CodeGen/Generic/2009-04-10-SinkCrash.ll
Chris Lattner 296185c264 fix two problems with machine sinking:
1. Sinking would crash when the first instruction of a block was
   sunk due to iterator problems.
2. Instructions could be sunk to their current block, causing an
   infinite loop.

This fixes PR3968
