rs6000: Disable -m[no-]direct-move (PR85293)
The -mno-direct-move option causes a lot of problems, since it forces
us to be able to generate code for p8 and up with some crucial
instructions missing. This patch removes the -m[no-]direct-move
options so that the user cannot put us into this unexpected situation
anymore. Internally we still have all the same flags, and they are
automatically set based on -mcpu; getting rid of that is a lot more
work and will have to wait for GCC 9 (in some places the flag is used
to see if we are compiling for a p8 _at all_).

* config/rs6000/rs6000.opt (mdirect-move): Make deprecated.
