Up until now we can only inline based on JSFunction, because of the way
the deoptimization works.  With this change we will be able to inline
based on the SharedFunctionInfo and materialize the JSFunction from a

This change rewrites regexps like (ab|ac|z|ad|ae|af) into (a[b-f]|z).  We can only reorder disjunctions like this for case-dependent regexps.  For case-independent regexps, the disjunctions should be pre-sorted for best results.

The initial implementation of this method takes a couple shortcuts:
- At some points in the spec, we should be making a reference to
  "Table 49" and instead do property lookup on the constructor.
  This is an issue with some other TypedArray methods too.
- The spec indicates that, if constructor and @@species haven't been
  messed with in particular ways, then there should be a memcpy
  from the old to the new. That fast path is not implemented here
  in this patch, but because V8 doesn't canonicalize NaN, the result
  isn't observably different.
