Hi.

  No one back end does not use PREFERRED_OUTPUT_RELOAD_CLASS macro now, this
patch remove it. The TARGET_PREFERRED_RELOAD_CLASS target hook should be use 
instead.

  The patch has been bootstrapped on and regression tested on
x86_64-unknown-linux-gnu for c and c++.

  This patch is pre-approved and should be committed within a week if no
objections.

        * doc/tm.texi.in (PREFERRED_OUTPUT_RELOAD_CLASS): Remove.
        * doc/tm.texi: Regenerate.
        * targhooks.c (default_preferred_output_reload_class): Don't use
        PREFERRED_OUTPUT_RELOAD_CLASS macro.
        * system.h (PREFERRED_OUTPUT_RELOAD_CLASS): Poison.



Anatoly.
