Bug#50057: SHOW PROFILE CPU for Windows

On QA request, adding test that causes new code to be called. 
Even if we cannot validate the result, this will at least increase the code coverage.

mysql-test/r/show_profile.result

+SET profiling = 1;
+SELECT 1;
+1
+1
+SHOW PROFILES;
+Query_ID	Duration	Query
+1	#	SELECT 1
+SHOW PROFILE FOR QUERY 1;
+SHOW PROFILE CPU FOR QUERY 1;
+SET profiling = 0;

mysql-test/t/show_profile.test

+#
+# Test for show profiles
+# No meaningful check is possible. 
+# So it only checks that SET profiling is possible and
+# that SHOW PROFILES, SHOW PROFILE FOR QUERY and SHOW PROFILE CPU FOR QUERY
+# do not cause syntax errors. It also increases code coverage for sql_profile.cc
+
+--source include/have_profiling.inc
+SET profiling = 1;
+SELECT 1;
+--replace_column 2 #
+SHOW PROFILES;
+--disable_result_log
+SHOW PROFILE FOR QUERY 1;
+SHOW PROFILE CPU FOR QUERY 1;
+--enable_result_log 
+SET profiling = 0;
