bmeurer 19b3943607 [turbofan] ChangeFloat64ToTagged shouldn't canonicalize. ... This matches current Crankshaft/fullcodegen behavior more closely and thus reduces the chances that we run into unnecessary polymorphism due to the field representation tracking in our object model. Drive-by-fixes: Make sure the JSRegExp::lastIndex field stays Smi if possible (otherwise we tank the regexp benchmark in Octane).
