David Green 5dc9c39ac1 [GlobalISel] Check the correct register in sextload OneUse check. (#114763) ...

This fixes a bug that started triggering after #111730, where we could
remove a load with multiple uses. It looks like the match should be
checking the other register in a one-use check.

  %SrcReg = load..
  %DstReg = sign_extend_inreg %SrcReg
