port cb9b8010 (r33582) original commit message: The previous versions of Math.max and Math.min made it difficult to optimize those (that's why we already have custom code in Crankshaft), and due to lack of ideas what to do about the variable number of arguments, we will probably need to stick in special code in TurboFan as well; so inlining those builtins is off the table, hence there's no real advantage in having them around as "not quite JS" with extra work necessary in the optimizing compilers to still make those builtins somewhat fast in cases where we cannot inline them (also there's a tricky deopt loop in Crankshaft related to Math.min and Math.max, but that will be dealt with later). So to sum up: Instead of trying to make Math.max and Math.min semi-fast in the optimizing compilers with weird work-arounds support %_Arguments %_ArgumentsLength, we do provide the optimal code as native builtins instead and call it a day (which gives a nice performance boost on some benchmarks).
