  Log Message:
  -----------
  [NVPTX] Use 0 immediate for i1 trunc, cleanup dead code (#135646)

Update the instruction selection for truncation to i1 to use "setp.ne
%v, 0" as the zero immediate is a preferable canonical form. Also remove
some dead code relating to the "set" instruction which we do not
actually support currently.
