-Currently, powerpc-linux gcc -Os -mno-multiple uses out-of-linux gpr
-save and restore functions when saving/restoring just one gpr. That's
-quite silly since the function call requires more instructions and is
-slower than an inline save/restore. The only case where it might win
-is when no fprs are restored and the restore function can tear down
-the frame and exit (also loading up lr on ppc64). I guess that's how
-GP_SAVE_INLINE came to be like it is, ie. it's optimised for the
-common case using ldm in the prologue and no fprs. Still, it isn't
-difficult to choose the best combination in all cases, but it does
-mean different logic is needed for restores. I could have implemented
-GP_RESTORE_INLINE and FP_RESORE_INLINE macros but it seemed simpler to
-just move everything into the one place the macros are invoked. AIX
-and Darwin register cutoff doesn't change with this patch.
-
-This patch also enables out-of-line restores in cases that were
-previously disabled due to using inline saves.
-
-Bootstrapped and regression tested powerpc-linux. OK to apply?

- * aix.h (FP_SAVE_INLINE, GP_SAVE_INLINE): Delete.
- * darwin.h (FP_SAVE_INLINE, GP_SAVE_INLINE): Delete.
- * sysv4.h (FP_SAVE_INLINE, GP_SAVE_INLINE, V_SAVE_INLINE): Delete.
- * config/rs6000/rs6000.c (V_SAVE_INLINE): Delete.
- (rs6000_savres_strategy): Reimplement GP/FP/V_SAVE_INLINE logic.
- For ELF targets, use out-of-line restores for -Os and any number
- of regs if the restore exits, and out-of-line gp save for two or
- more regs. Use save_reg_p to test for holes in reg restore set.
- Replace "#if" with "if".
