After https://codereview.chromium.org/1180433003 the code-size exceeeds
the limit for MIPS. We have some optimizations in place for MIPS64 that
will be ported back to MIPS, and will investigate other code-size
improvements so we can re-enable this test.

Two changes:
  - In ReportBootstrappingException, if all we have is a string, it seems
    better to print that than nothing.
  - In Factory::NewError, there's no use trying to call into the builtins if
    compilation of the builtins is causing the exception (this currently
    results in a cryptic segfault if we trigger, say, a ReferenceError when
    executing builtins script during bootstrapping).

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.
