  |     LRA: Fix eliminate regs into a subreg inside a debug insn [PR123295]
  |     
  |     So the problem here is during LRA we are eliminating argp and trying to
  |     simplify the RTL as we go but inside a debug insn, almost all subreg
  |     are valid due to gen_lowpart_for_debug done during debug insn simplification.
  | ... 17 lines of the commit log omitted.
