When generating snapshot on a machine with a different page size than
the target machine, we can run into problems as the v8 page area size
changes. This is because v8 has page guards which depend on os page
size, so if the target has larger os page, v8 page area is smaller and
may not fit the contents.
The solution proposed here is adding a flag, v8_os_page_size, that
would, if used, override local os page size and use the one specified
during snapshot generation.

Having presubmit called from within the test runner often
requires logic to remove the call again.
After the GN transition it would be better if presubmit is
called by a wrapper script if needed at all. It is run
on upload and on the tryservers anyways.

This fixes the Python include path after the GYP files have been
relocated into another directory. It only affects 'make native', other

This will allow to pull in gyp as a deps to the same location
as chromium (tools/gyp not build/gyp), needed for gn switch.
This is the first step of a 3-way move.
1) Copy v8.gyp in v8
2) Update references in embedders (follow up)
3) Remove old v8.gyp (follow up)

Fixes for misnamed toolchain from https://github.com/appcelerator/v8_titanium.
Added a way to specify the NDK path since the Mac versions of the NDK aren't checked into the tools repo.
Disabled a few dependencies which do not build on the Mac but which aren't needed for building usable V8 static libraries.
Made the including of libdl and librt omitted for Mac hosted builds.

A startup snapshot is considered cold when it does not contain any
function code. We can now create a warm startup snapshot from a cold one
by running a warm-up script. Functions exercised by the warm-up script
are compiled and its code included in the warm startup snapshot. Side
effects caused by the warm-up script does not persist.

This is the first of several commits to contribute Linux on z Systems
(s390/s390x) port of V8. We will be breaking up the changes into several
(hopefully) logical commits.
This commit contains the changes to V8 Makefile and build toolchains to
introduce S390 macros and compiler options. Just for awareness for reviewers
is that s390 is 31-bit (not 32!) big-endian platform on Linux on z. (MSB of address
is used to distinguish between 24-bit vs 31-bit addressing!) s390x is
64-bit Linux on z. Names follow the general linux convention on the platform.
A quick roadmap on upcoming commits:
- Add \#include of S390 header files in common files
- S390 related tests + tooling changes
- printf macro for printing size_t values.
- S390 platform-specific code generation code (bulk of changes!)

It prepares for using this script outside of v8, e.g. in a
chromium hook.
The script is intended to run as a hook and will create
version_gen.cc if the content has changed.
Changes to gyp and gn files can land as a follow up, once
calling the hook on the chromium side has landed.

All builders that used level 1 should meanwhile define
v8_enable_slow_dchecks, and so they can use level 2 without losing
coverage. Level 2, however, is considerably faster, so we want to use it
on those builders as well. The make optdebug setting is not affected by
this change.

The logic was supposed to trigger a rebuild if the CXX variable is
changed. However, it failed to track the other compiler related
variables, and, what is worse, conflicted with the clang=1 gyp setting
by forcing CXX to g++
The new logic just relies on tracking GYP defines, and checks whether
the CXX binary - if set - has a target different from the host
architecture.
