Alexander Barkov c5d8b9963a MDEV-36716 A case expression with ROW arguments in THEN crashes 
The patch for SYS_REFCURSOR (MDEV-20034) overrode these methods:
- Item_func_case_searched::check_arguments()
- Item_func_if::check_arguments()

to validate WHEN-style arguments (e.g. args[0] in case of IF) for being
able to return a boolean result.

However, this unintentionally removed the test for the THEN-style arguments
that they are not expressions of the ROW data type.

This led to a crash inside Type_handler_hybrid_field_type::aggregate_for_result
on a DBUG_ASSERT that arguments are not of the ROW data type.

Fix:

The fix restores blocking ROW expressions in the not supported cases,
to avoid the DBUG_ASSERT and to raise an SQL error instead.

Blocking ROW_RESULT expressions is done per Item_func_case_expression
descendant individually, instead of blocking any ROW_RESULT arguments
at the Item_func_case_expression level.

The fix is done taking into account the upcoming patch for associative arrays
(MDEV-34319). It should be possible to pass associative array expressions into
some hybrid type functions, where ROW type expressions are not possible.

As a side effect, some lecagy ER_OPERAND_COLUMNS changed to
a newer ER_ILLEGAL_PARAMETER_DATA_TYPE_FOR_OPERATION

Changes in the top affected class Item_func_case_expression:

- item_func.h:
  Overriding Item_func_case_expression::check_arguments() to return false,
  without checking any arguments. Descendant validate arguments
  in a various different ways. No needs to block all non-scalar data type at
  this level, to prevent disallowing associative arrays.

Changes in descendants:

- item_cmpfunc.cc:
  Adding a test in Item_func_case_simple::aggregate_switch_and_when_arguments()
  preventing passing ROW_RESULT expression in predicant and WHEN in a
  simple CASE:
    CASE predicant WHEN when1 THEN .. WHEN when2 THEN .. END;
  This is not supported yet. Should be preferrably fixed before MDEV-34319.

- item_cmpfunc.cc:
  Calling args[0]->type_handler()->Item_hybrid_func_fix_attributes()
  from Item_func_nullif::fix_length_and_dec().
  This prevents a ROW expression to be passed to args[0] of NULLIF().
  But will allow to pass associative arrays.

  args[1] is still only checked to be comparable with args[0].
  No needs to add additional tests for it.

- item_cmpfunc.h:
  Adding a call for Item_hybrid_func_fix_attributes() in
  Item_func_case_abbreviation2::cache_type_info().
  This prevents calling the descendant functions with
  a ROW expression in combination with an explicit NULL
  in the THEN-style arguments (but will allow to pass associative arrays):

    IFNULL(row_expression, NULL)
    IFNULL(NULL, row_expression)
    IF(switch, row_expression, NULL)
    IF(switch, NULL, row_expression)
    NVL2(switch, row_expression, NULL)
    NVL2(switch, NULL, row_expression)
  Adding a THD* argument into involved methods.

- item_cmpfunc.h:
  Overriding Item_func_case_abbreviation2_switch::check_arguments() to
  check that the first argument in IF() and NVL2() can return bool.
  Removing Item_func_if::check_arguments(), as it become redundant.

- sql_type.cc:
  Fixing sql_type.cc not to disallow items[0] with ROW_RESULT.
  This makes it call Item_hybrid_func_fix_attributes() at the end,
  which block ROW arguments into THEN-style arguments of hybrid functions.
  But this will allow to pass Type_handler_assoc_array expressions.

- sql_type.cc:
  Changing Type_handler_row::Item_hybrid_func_fix_attributes to raise the
  ER_ILLEGAL_PARAMETER_DATA_TYPE_FOR_OPERATION error instead of the DBUG_ASSERT.
