[PATCH 6/9] trace2:experiment: clear_ce_flags_1

[Jeff Hostetler via GitGitGadget]

From: Jeff Hostetler <jeffh...@microsoft.com>

The clear_ce_flags_1 method is used by many types of calls to
unpack_trees(). Add trace2 regions around the method, including
some flag information, so we can get granular performance data
during experiments.
