When comparing objects which get printed to very long strings (e.g.
collections like vectors), it's much more readable if they get printed
to individual lines. Differences are much easier to spot then.
This CL refactors the CHECK/DCHECK macros to print the left hand side
and right-hand side in individual lines if any of them is longer than 50
characters.
To that end, the {PrintCheckOperand} method (only used from
{MakeCheckOpString}) is changed to return the string directly instead of
printing to an output stream.

MSVC 2015 and 2017 implement std::is_trivially_copyable, but not
correctly. Hence, reimplement it using more low-level primitives.
For stdlibc++ versions below 5.0, we already have a workaround for the
missing support of std::is_trivially_copyable, but this is an unsound
approximation, because it is ignoring move constructor, move assignment
and copy assignment. Therefore, do not use this approximation for
asserting trivial copyability of a type.
Finally, add unittests for the new is_trivially_copyable
implementations.

gcc and clang (and the standard) don't allow implicit conversion of
function pointers to object pointers. MSVC does allow that, and since
system headers require this to work, clang-cl allows it too -- but
it emits a -Wmicrosoft-cast warning (which we currently suppress in
the Chromium build, but which we want to enable.)
As a side effect, when printing a function pointer to a stream, MSVC
(and clang-cl) will pick the operator<<(void*) overload, while gcc
and clang will pick operator<<(bool) since the best allowed conversion
they find is from function pointer to bool.
To prevent the clang-cl warning, we need to make sure that we never
directly print a function pointer to a stream. In v8, this requires
two changes:
1. Give PrintCheckOperand() an explicit specialization for function
pointers and explicitly cast to void* there. This ports
https://codereview.chromium.org/2515283002/ to V8, and also fixes a
bug on non-Windows where DCHECK() of function pointers would print
"(1 vs 1)" instead of the function's addresses.
(The bug remains with member function pointers,
where it's not clear what to print instead of the 1.)
2. has_output_operator<T> must not use operator<< on its argument
in an evaluated context if T is a function pointer. This patch
modifies has_output_operator<> to use an unevaluated context instead,
which is simpler than the current approach (and matches what Chromium's
base does), but changes behavior in minor (boring) ways
(see template-utils-unittest.cc), since operator<<() is now
called with a temporary and only operator<<() implementations callable
with a temporary are considered.
A more complicated but behavior-preserving alternative would be to
add an explicit specialization for function pointers. You can see
this variant in patch set 1 on gerrit.

It was already always high-resolution on POSIX but was never high
resolution on Windows. Windows does support low latency high-resolution
timers for the majority of our user base.
TimeTicks::HighResolutionNow() was only explicitly requested in testing
frameworks. As such I left the call in place but made it DCHECK that
it's running on a Windows machine on which high-resolution clocks are
used. This confirms that none of our test fleet has regressed with this
change (the previous HighResolutionNow() used to be slightly more
aggressive and also do it in a few configurations where we now fallback
to low-resolution now).
This implementation was copied as-is (modulo minor v8 API
compatibility tweaks). These implementations were the same in the
past but had diverged when, sadly, the same bug was fixed separately
years apart, in Chromium and V8:
chromium: https://codereview.chromium.org/1284053004 + https://codereview.chromium.org/2393953003
v8: https://codereview.chromium.org/1304873011
This is a prerequisite to add metrics around parallel task execution
(low-resolution clocks are useless at that level, but we also don't want
to incur high-latency clocks on machines that can't afford it cheaply).

This commit is a step toward enabling test-run-wasm-simd tests for MIPS.
36 of those were failing in V8 builtin simulator because some instructions
were not implemented. Also there are minor fixes to some of the already
implemented instructions.
This commit has only 32-bit implementation. After review I will add
64-bit version.

This is a reland of b73ee3344a
Original change's description:
> [Memory] Use OS::Allocate for all OS memory allocations.
>
> - Eliminates OS::ReserveRegion and OS::ReserveAlignedRegion.
> - Changes OS::Allocate to take alignment parameter, reorders parameters
> to match page_allocator.
> - Since the size of memory allocation can be deduced, don't return the
> amount of memory allocated.
> - Changes reservation of aligned address space. Before we would reserve
> (size + alignment) rounded up to page size. This is too much, because
> maximum misalignment is (alignment - page_size).
> - On Windows and Cygwin, we release an oversize allocation and
> immediately retry at the aligned address in the allocation. If we
> lose the address due to a race, we just retry.
> - Clean up all the calls to OS::Allocate in codegen and tests by adding
> helper AllocateSystemPage function (allocation.h) and
> AllocateAssemblerBuffer (cctest.h).
> - Changes 'assm' to 'masm' in some targets for consistency when using
> a macro-assembler.
>
> - Eliminates OS::ReleaseRegion, replacing with calls to OS::Free.
> - Adds bool return value to OS::Free.
> - Cleans up types of flags, protection on Windows and Cygwin.
