This CL tries to reduce as much as possible the emission of Float64
operations in the inlining of DataView methods.

It adds CheckSmi calls guarding the main variables that the
methods use, and deopts back to the baseline when outside of Smi range.
This should happen extremely rarely anyway, since we don't allow
ArrayBuffers to be larger than that by default.
