New issue 4184 by [email protected]: Significant portion of Blink test
runtime is spent in creating/configuring ObjectTemplates/FunctionTemplates
https://code.google.com/p/v8/issues/detail?id=4184
In particular, we spend lots of time dealing with Map transitions (and the
allocations related to them). It seems like we might be able to leverage
the information in ObjectTemplates and FunctionTemplates to create the
proper Map upfront. Perhaps this was already investigated at some point?
Besides speeding up test running it's possible that this could have an
impact on real web pages.
Elliott will attach the profile he ran that pointed at this stuff.
