      [CodeGenPrepare] Reset the debug location when promoting trunc(s)
      
      The promotion machinery in CGP moves instructions retaining
      debug locations. When the transformation is local, this is mostly
      correct, but when instructions are moved cross-BBs, this is not
      always true and causes jumpiness in line tables. This is the first
      of a series of commits. sext(s) and zext(s) need to be treated
      similarly.
