[RS6000] e500 part of pr71680
The fallback part of HARD_REGNO_CALLER_SAVE_MODE, choose_hard_reg_mode,
returns DFmode for SImode when TARGET_E500_DOUBLE. This confuses
lra when attempting to save ctr around a call.
PR target/71680
* config/rs6000/rs6000.h (HARD_REGNO_CALLER_SAVE_MODE): Return
SImode for TARGET_E500_DOUBLE when given SImode.
