Recreated the BCJ test files for x86 and SPARC. The old files

were linked with crt*.o, which are copyrighted, and thus the
old test files were not in the public domain as a whole. They
are freely distributable though, but it is better to be careful
and avoid including any copyrighted pieces in the test files.
The new files are just compiled and assembled object files,
and thus don't contain any copyrighted code.
