	PR rtl-optimization/35232
	* reload1.c (reg_reloaded_call_part_clobbered): Clarify comment.
	(forget_old_reloads_1, forget_marked_reloads): Don't clear
	reg_reloaded_call_part_clobbered here.
	(reload_regs_reach_end_p): New function.
	(reload_reg_rtx_for_input): New variable.
	(reload_reg_rtx_for_output): Likewise.
	(emit_input_reload_insns): Use reloadreg rather than rl->reg_rtx
	when reassigning a pseudo register.  Load reloadreg from 
	reload_reg_rtx_for_input, moving the mode and register
	calculation to...
	(do_input_reload): ...here.  Use the mode-adjusted reg_rtx
	instead of the original when deciding whether an input reload
	would be a no-op or whether an output reload can be deleted.
	(emit_output_reload_insns): Use the mode-adjusted reg_rtx
	when setting up new_spill_reg_store.  Load it from
	reload_reg_rtx_for_output, moving the mode and register
	calculation to...
	(do_output_reload): ...here.  Use the mode-adjusted reg_rtx
	instead of the original when deciding whether an output reload
	would be a no-op.  Do the same when modifying insn notes.
	Use rtx_equal_p instead of == to compare the registers.
	(inherit_piecemeal_p): Take a mode and two register numbers
	as argument.
	(emit_reload_insns): Clear new_spill_reg_store for every hard
	register in the reload register.  Remove spill registers
	from reg_reloaded_valid before considering whether to record
	inheritance information for them.  Use reload_reg_rtx_for_output
	instead of reg_rtx when recording output reloads.  Use
	reload_reg_rtx_for_input instead of reg_rtx when recording
	input reloads.  Set or clear reg_reloaded_call_part_clobbered
	at the same time as setting reg_reloaded_valid.
	(delete_output_reload): Add a new_reload_reg parameter and use it
	instead of rld[j].reg_rtx.
	(emit_input_reload_insns, do_input_reload, do_output_reload): Adjust
	calls accordingly.
