unknown 377d710296 BUG#47418 RBR fails, failure with mixup of base/temporary/view 
'CREATE TABLE IF NOT EXISTS ... SELECT' statement were causing 'CREATE
TEMPORARY TABLE ...' to be written to the binary log in row-based 
mode (a.k.a. RBR), when there was a temporary table with the same name.
Because the 'CREATE TABLE ... SELECT' statement was executed as 
'INSERT ... SELECT' into the temporary table. Since in RBR mode no 
other statements related to temporary tables are written into binary log,
this sometimes broke replication.

This patch changes behavior of 'CREATE TABLE [IF NOT EXISTS] ... SELECT ...'.
it ignores existence of temporary table with the 
same name as table being created and is interpreted
as attempt to create/insert into base table. This makes behavior of
'CREATE TABLE [IF NOT EXISTS] ... SELECT' consistent with
how ordinary 'CREATE TABLE' and 'CREATE TABLE ... LIKE' behave.

#
# Testing the behavior of 'PREPARE', 'DDL', 'EXECUTE' scenarios
#
# Background:
# In a statement like "select * from t1", t1 can be:
# - nothing (the table does not exist)
# - a real table
# - a temporary table
# - a view
#
# Changing the nature of "t1" between a PREPARE and an EXECUTE
# can invalidate the internal state of a prepared statement, so that,
# during the execute, the server should:
# - detect state changes and fail to execute a statement,
# instead of crashing the server or returning wrong results
# - "RE-PREPARE" the statement to restore a valid internal state.
#
# Also, changing the physical structure of "t1", by:
# - changing the definition of t1 itself (DDL on tables, views)
# - changing TRIGGERs associated with a table
# - changing PROCEDURE, FUNCTION referenced by a TRIGGER body,
# - changing PROCEDURE, FUNCTION referenced by a VIEW body,
# impacts the internal structure of a prepared statement, and should
# cause the same verifications at execute time to be performed.
#
# This test provided in this file cover the different state transitions
# between a PREPARE and an EXECUTE, and are organized as follows:
# - Part 1: NOTHING -> TABLE
# - Part 2: NOTHING -> TEMPORARY TABLE
# - Part 3: NOTHING -> VIEW
# - Part 4: TABLE -> NOTHING
# - Part 5: TABLE -> TABLE (DDL)
# - Part 6: TABLE -> TABLE (TRIGGER)
# - Part 7: TABLE -> TABLE (TRIGGER dependencies)
# - Part 8: TABLE -> TEMPORARY TABLE
# - Part 9: TABLE -> VIEW
# - Part 10: TEMPORARY TABLE -> NOTHING
# - Part 11: TEMPORARY TABLE -> TABLE
# - Part 12: TEMPORARY TABLE -> TEMPORARY TABLE (DDL)
# - Part 13: TEMPORARY TABLE -> VIEW
# - Part 14: VIEW -> NOTHING
# - Part 15: VIEW -> TABLE
# - Part 16: VIEW -> TEMPORARY TABLE
# - Part 17: VIEW -> VIEW (DDL)
# - Part 18: VIEW -> VIEW (VIEW dependencies)
# - Part 19: Special tables (INFORMATION_SCHEMA)
# - Part 20: Special tables (log tables)
# - Part 21: Special tables (system tables)
# - Part 22: Special tables (views temp tables)
# - Part 23: Special statements
