But at the moment it does not.
I do prefer to leave that task for the one that
adds opus decoder functions.

Also this change alone would break compilation, since
it also requires changing the libavcodec/x86/Makefile
and adding the guard inside the opus_dsp_init.c

Another option is to have "opus_enc_dsp_init.c" and call
the function "ff_opus_enc_dsp_init_x86()".

Do tell me which option do you prefer
and do you insist on v7 just for that.
