Don't start new steps recursively if a step is already in progress. Having this property on a space is not sufficient, as an allocation is a global (heap-wide) event. Computing the next step size, for example is a property of all observers in existence rather than the spaces in existence. In this case a failure was due to the fact that we attempted to compute the next step size while a given observer was mid-way through its step triggered from a different space. bytes_to_next_step_ was partially updated at that point.

After deprecating the top-file Makefile, "make tags" cannot easily be used any more. Moving the tags-related rules out to a separate Makefile allows to continue using it using either "make -f tools/Makefile.tags tags", or including it in your own Makefile.

Sigurd Schneider authored
With the new builtin optimization guard we can just speculatively assume that the index passed to String#charAt and String#charCodeAt (in optimized code) is going to be within the valid range for the receiver. This is what Crankshaft used to do, and it avoids Smi checks on the result for String#charCodeAt, since it can no longer return NaN. This gives rise to further optimizations of these builtins (i.e. to completely avoid the tagging of char codes), and by itself already improves the regression test originally reported from 650ms to 610ms.
