f7b6e73146 igzip: Improve igzip_rand_test compress_multi_pass by modifying in buffer 
Modify igzip_rand_test to test that data after next_in can be modified without
producing incorrect compressed data.

e79c57c7e3 igzip: Fix issue with isal_create_hufftables_subset 
isal_create_hufftables_subset failed to generate length symbols, but should
generate those symbols as a histogram does not guarantee finding all lengths
found in compression

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.
