[Cogl] [PATCH] journal: Add a uprof timer around the _flush() discard

[Robert Bragg]

From: Robert Bragg <robert at linux.intel.com>

This adds a uprof timer around the _cogl_journal_discard() at the end of
_cogl_journal_flush() since this sometimes takes a significant
proportion of the time to flush the journal.
