r600g,compute: provide local copy of functions from ac_binary.c
This is a verbatim copy of the code. The functions can be cleaned up since r600 does not use all the stuff that gcn does. The symbol names have been changed since we still use ac_binary.h header (for struct definition) v2: Add ifdef guard around r600_binary_clean call (Aaron) Remove stray comment Signed-off-by: Jan Vesely <jan.vesely@rutgers.edu> Tested-By: Aaron Watry <awatry@gmail.com> Reviewed-by: Emil Velikov <emil.velikov@collabora.com>
