BUG#26495791: CONTRIBUTION: EXPAND TEST SUITE TO INCLUDE CRC32 TESTS

Browse Source 
From mysql-server:
09fdfad50764ff6809e7dd5300e9ce1ab727b62a
e90ae1707e0ca46abc775d1680d1856c4be38b66

described in http://github.com/mysql/mysql-server/pull/157

Apart from external contribution I have added few more additional testcases
for CRC32() function, which are given below.

New Testcases added:
  ->Verify the crc value of various numeric and string data types(int,
      double, blob, text, json, enum, set)
  ->Verify the crc value when expressions having comparison_operators
      and logical_operators
  ->Verify the crc value for the expression having string_functions,
      arithmetic_functions, json_functions
  ->Verify the crc value for the expression having Geometry functions
      like POINT, LINESTRING, MULTILINESTRING, POLYGON, MULTIPOLYGON
  ->Verify the crc value generated from stored procedures, functions,
      triggers, prepare statement, views.

Fix:
Patch based on contribution by Daniel Black (Github user: grooverdan)
