Improves code size of generated regexp in TestSizeOfRegExpCode test by 33%.

Execution time of the same test improved by ~10%.

Utilizing code range for mips64 enable us to use J/JAL
instructions for long branches.

This should prevent bugs caused by missing super calls in
overridden methods. The assumption is that methods of
different indicators are independent.

This prepares for properly rerunning tests. Currently when
tests are rerun, the same test object is reused. This
will be changed in a follow up.

Use the new TranslatedState and friends, which work at a higher level
than the TranslationIterator, which will make it easier to change the
deoptimization commands in subsequent CLs.

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.

These values were computed by the parser and hence out of sync with any
visitor over the AST. Our AST visitor aborts visitation of statement
lists as soon as a jump statement has been reached. Now handler tables
are guaranteed to be dense and fully populated.
