... and do not artificially add at least one dummy.js file.
Until this CL we used to ensure the existence of at least one 'extra
native' by appending a short dummy.js file if v8_extra_library_files
was empty. This file is uselessly compiled and run at startup.
This CL removes that mechanism along with a minor tweak to handle an
empty natives blob.

We no longer implement part of the debugger in JS. Therefore we can
remove the infrastructure to support this in the bootstrapper.
Also includes some drive-by cleanups.

The primary purpose of this is to untangle a circular dependency
objects.h -> handles.h -> objects.h. Most compilation units only
need message-template.h, without the rest of messages.h.
Bonus: change the enum to an enum class for improved type safety.

IsDebuggerFile() marked all modules as debug ones, which triggered

If a key is a substring of an earlier value, then the earlier value
will unintentionally be clobbered. For example with:
macro SET_PRIVATE(obj, sym, val) = (obj[sym] = val);
SET_PRIVATE(iterator, arrayIteratorObjectSymbol, object);
if the mapping is:
{'val': 'object',
'obj': 'iterator',
'sym': 'arrayIteratorObjectSymbol'}
then 'obj' -> 'iterator' will clobber 'val' -> 'object', resulting in
'val' -> 'iteratorect'. To fix this, replace all substitutions
simultaneously.

When introducing experimental extras I forgot to update this check. That resulted in experimental extras running through the steps normally reserved for non-extra natives: macro and constant expansion, validation, and minification. This causes problems since per the linked bug minification is buggy.

- Modify js2c to accept --js and --nojs,
- modify mksnapshot to accept --startup_src
(instead of a positional parameter, so that it can be omitted),
- modify v8.gyp to use the above so that no target has multiple
output dependencies, and
- update GN to use the switches above.
(I have not succeeded in fixing the GYP->make translator to properly map
multi-output rules, so that they work as expected in all edge cases.
This CL signals defeat on that front, and instead I rewrite the GYP
file to avoid that situation in the first place.)

Without this change, V8 won't build on RHEL/CentOS 6 because the distro
python is too old to know about the argparse module.
Can this commit be cherry-picked to the 4.4 branch? It should apply

Instead of making them an extra option that gets passed in and compiled
at the end of the natives file for a given run of js2c, we now make them a
separate run of js2c with a separate natives file output.
This natives file output is then compiled in the bootstrapper. It is not part
of the snapshot (yet), but instead is treated similar to the experimental
natives, just without any of the complexity that comes from tieing the
behavior to flags. We also don't need counterparts to
InitializeExperimentalGlobal and InstallExperimentalNativeFunctions (yet?).
This fixes the issue with https://codereview.chromium.org/1129743003 by making
the dummy file that is generated for snapshots with no extras (or no experimental
features) nonempty.

js2c.py now distinguishes between the JS internal sources and any
extra scripts passed in. The latter only get validation and
comment/trailing whitespace removal applied now.
Also added a --js option to js2c.py, which will output a JS file
instead of a C++ file, for debugging. (I got tired of finding the
generated .cc file and extracting its byte array so that I could feed
it to a separate helper script I wrote.)

These methods for used for compressed libraries, where GetSource* functions
contained the compressed sources and [GS]etRawSource* the uncompressed
sources. This is dead code since the API no longer supports compression.
(If you need/want compressed sources, use the external startup data and
compress/uncompress on the Embedder's side.)
