Hiroshi Yamauchi 4d59570b59 [ProfileSummary] Add the PartialProfileRatio field in ProfileSummary metadata.
Summary:
PartialProfileRatio approximately represents the ratio of the number of profile
counters of the program being built to the number of profile counters in the
partial sample profile. It is used to scale the working set size under the
partial sample profile to reflect the size of the program being built and to
improve the working set size heuristics.
