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.

This updates the test runner to run all tests in both sloppy
and strict mode.

It also marks the test in the status file as failing in
sloppy mode even if all it does is marking the test as
[PASS, FAIL]. A future CL will have to validate that the
tests pass and fail in the correct mode.

crrev.com/1016603004 should have fixed the issues that broke this last time.

Notes:
- The current functionality is meant to stay. If you prefer the old way,
  just set v8_use_external_startup_data=0.
- You might notice this if you call d8 via PATH. Either explicitly tell d8
  where your external snapshot/built-ins are, or change the build options
  as above.
- This follows Chromium practice, that mostly uses this feature these days.
- Other platforms to follow later.

This was already public in a non-component build. This means that targets
dependent on the "v8" target can take the results of the snapshot as inputs.

This also renames the component mode checking from keying off of the
component_mode string to checking the is_component_build flag, which is now the
recommended way to do this check.
