Issue 102: if (A == undefined) is slow
http://code.google.com/p/v8/issues/detail?id=102
New issue report by [EMAIL PROTECTED]:
codegen-ia32.cc, VisitCompareOperation generates inlined code for:
1) one-side is null; 2) typeof and string; 3) inlined smi's.
A command pattern is check a value against 'undefined'. Currently it falls
into the slow path that calls EQUALS js function, which calls 'toString' or
'toNumber' again. The worst part in a browser is that, DOMWindow.toString
needs domain security check.
