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!)

Add control for the ignition test suites. This will be
followed by a change on the infra side that targets the
ignition set instead of the hardcoded mjsunit.
After that, cctest can be enabled in a separate CL. This CL
already includes the logic for running cctest for ignition
on swarming.

Updated toolchain.gypi to support v8 using CLANG on MIPS. These changes
include using integrated assembler with CLANG, and disabling options
used by GCC which are not supported by CLANG.

This is based on the Skia Implementation.
More on the project can be found here:
https://docs.google.com/a/chromium.org/document/d/1_4LAnInOB8tM_DLjptWiszRwa4qwiSsDzMkO4tU-Qes/edit#heading=h.p97rw6yt8o2j
The V8 Tracing platform will replace the isolate->event_logger().
But since the current embedders (namely chromium) currently use the isolate->event_logger, I made the default implementation (event-tracer) call into isolate->event_logger if an event_logger was set.
Once the embedders properly implement the interface (for example in chromium it would look like this: https://codereview.chromium.org/707273005/), the default implementation will be doing nothing.
Once the embedders side is fixed, we will change how V8 uses the tracing framework beyond the call from Logger:CallEventLogger. (which would also include a d8 implementation)

update.sh is gone in chromium, and using update.py will do the right
thing both before and after the deletion in chromium (previously,
update.py used to call update.sh internally on non-win).
This also has the benefit of working on Windows.
No intended behavior change.

Changing this value is not guaranteed to work yet, but it needs to be

Set "no recover" in diagnostic mode to keep triggering
crashes. Otherwise, the v8 test driver won't notice tests
as failing.
Also port some common sanitizer cflags to cfi - those can be
removed on the build side afterwards.

This adds the unittests to the "default" test set. Now that
the "default" and the DEFAULT_TESTS (i.e. runner with
no arguments) are the same, removed DEFAULT_TESTS and use
TEST_MAP["default"] instead.
On the bots, where unittests and default were run in
separation before, the explicit unittests step should now
be skipped.
This is necessary for swarming, as the unittests step is
too small to justify its own swarming job.

This is a simplified version of chromium's isolate driver:
- 'prepare' will create a *.isolate.gen.json with the
arguments to be used later.
- other modes will just be passed through to the isolate
script.

v8 is optimized for speed. Because GCC LTO merges flags at link time,
we disable LTO to prevent any -O2 flags from taking precedence over v8's
-Os flag. However, LLVM LTO does not work this way so we keep LTO enabled
under LLVM.
This fixes the ARM build in the cfi_vptr==1 configuration, which requires
LLVM LTO.

Embedders would use these for features which must be able to be turned
off at runtime, despite being compiled into V8. They can be turned on
and off by the embedder using the --experimental_extras flag, e.g. via
v8::SetFlagsFromString.
