Subject: [PATCH 6/9] trace2:experiment: clear_ce_flags_1

From: "Jeff Hostetler via GitGitGadget" <[email-masked]>
Date: Tue, 20 Aug 2019 08:11:10 -0700 (PDT)

From: Jeff Hostetler <[email-masked]>

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.
