Relanding histogram static removal changes. This is a revert 
of http://src.chromium.org/viewvc/chrome?view=rev&revision=78925

The following is the original check-in and review.

Removed the static on all histogram macros. If this change
sticks, then we could stop using these macros and will change
all the code that use histogram macros.

BUG=76092
TEST=histogram unit tests and watch out if this change
has performance impact. We did a trial run of this patch
and we didn't see any impact in performance bots.
R=jar
