Cache the ranges_ vector and share the ranges_ vector
across histograms if the ranges in the ranges_ vector
is same. This change saves around 100k of memory in the
browser (around 400 histograms sharing the same ranges_
vector and each ranges_ vector has around 50 elements).
In each renderer process we are sharing ranges_ vector
for around 30 histograms (a savings of 6k of memory).
R=jar
TEST=histogram unit tests.
