Vlad added rs6000_secondary_memory_needed_mode for lra, and in so
doing broke reload's use of cfun-machine-sdmode_stack_slot in
rs6000_secondary_memory_needed_rtx (mode was no longer SDmode there).
Bootstrapped and regression tested powerpc64-linux, both with and
without -mlra. OK to commit?
PR target/60032
* config/rs6000/rs6000.c (rs6000_secondary_memory_needed_mode): Only
change SDmode to DDmode when lra_in_progress.
* gcc.target/powerpc/pr60032.c: New.
