[ASTERIXDB-2523][RT][COMP] add support for hashing array fields
- user model changes: no
- storage format changes: no
- interface changes: no
Details:
Add support for hashing array fields.
- Modified AMurmurHash3BinaryHashFunctionFamily and extracted the hashing
function
into a private named hashing function "GenericHashFunction". Added hashing
arrays.
- Modified hash join to include generating hash functions for the right branch
since now hash functions are type-dependent and cannot use the same hash
functions
generated for the left branch.
- Added test cases.
