Bug#42635: mysqldump includes views that were excluded using the \

	--ignore-table option

mysqldump would correctly omit temporary tables for views, but would
incorrectly still emit all CREATE VIEW statements.

Backport a fix from 5.1, where we capture the names we want to emit
views for in one pass (the placeholder tables) and in the pass where
we actually emit the views, we don't emit a view if it wasn't in that
list.
