Moved the afl fuzz test and added llvm fuzz tests including inflate

std makefile and libFuzzer installed.  Need to add checking and
support later when libfuzzer is more tightly integrated into the
compiler.

f78601adb9 igzip: Pick faster crc32 gzip function for sse4.2 machines 
For machines with sse4.2 but not avx we can choose a faster version of
crc32_gzip. For highly compressible files using gzip format (rfc 1952) this can
be a significant advantage.
