Wide suspends have a "wide" (or "extra-wide") bytecode at their offset,
rather than the suspend itself, so they were failing the return check.

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.

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.
