Comment #4 on issue 2365 by [email protected]: Comparing with a local
variable that is never assigned to is slow
https://code.google.com/p/v8/issues/detail?id=2365
This is a performance bug in CrankShaft. There is a special case for
comparing with literals that generates special code if the right hand side
is a literal. It should use the SSA value, which is known to be the
undefined value.
Relevant code in HOptimizedGraphBuilder::VisitCompareOperation
(hydrogen.cc:11087).
