The data I gathered for the JSC bug:
https://bugs.webkit.org/show_bug.cgi?id=99118#c15
suggests that this could have a real effect on web perf, as we have do some 24k of these needless hashings when loading a small docs.google.com spreadsheet.  The numbers I generated there were from a JSC build, but I expect them to be very similar for v8, since the profiles of v8/jsc are somewhat similar for this test.
