Exit early from the plugin execution of ALTER TABLE statements
on the replica nodes. This is to prevent re-execution of syscat
table population from the replica nodes which should only be
executed once by the primary node in a CS cluster setup.
ARM platforms. This patch resolves this issue and unifies AUX column
processing at x86 and ARM using tempate class SimdProcessor.
The patch also replaces uint16_t mask previously used in column.cpp and
SimProcessor code with a native masks that platform uses, e.g. __m128i
or __m128 on x86 and variety of masks on ARM.
To unify the processing I introduced a new filtering Compare Operator - COMPARE_NULLEQ.
with a 'c1 IS NULL semantics'.
* Sort test result so the test case would pass
* Server message has been changes
* Added schema name in query for rows in test case only. Also use lower case schema name
* Changed database to lower case
* Run test case in its own database to avoid table already exists error

This patch fixs the reported JIRA issue MCOL 5205, which consists of a wrong union type from two input Int types. The bug results in wrong unioned answers in CS. The fix includes more INT case discussions. Additionaly, this patch provides detailed unit tests for correctness in UNION processing with Int.

This patch improves the runtime performance of UNION processing in CS, as reported JIRA issue MCOL 4590. The idea of the optimization is to infer the normalize seperate functions beforehand and perform the normalization individually later, instead of a huge switch body of all normalization. This patch also cover engineering optimization, removing the hotspots in UNION processing. After application of this patch, the normalize part takes only about 25% of the whole UNION query in our experiment avg case.

The main CmakeLists.txt was using MY_CHECK_AND_SET_COMPILER_FLAG before the include. This works in-band with server because it was already included in server's CmakeLists.txt.
dbcon/mysql included curl as a build dependency. We don't build curl. It's a lib dependency. Not sure why it works in-band. One wouldn't think it should.
ARM and x86 differ in their default char signedness, namely x86's
char is signed and ARM's char is not. This difference breaks at least
breaks calShowPartitionByValue() udf.
