4f59eeda90 test: Add llvm fuzz testing 
Moved the afl fuzz test and added llvm fuzz tests including inflate
and round trip compress and inflate.  Currently only works with clang,
std makefile and libFuzzer installed.  Need to add checking and
support later when libfuzzer is more tightly integrated into the
compiler.
