8fb593047a Removed bogus threading test to make TSAN happy.
TSAN hits an internal assertion on a self-join, and the test is not
really that useful, so let's just remove it.

9a5ec9c57c Fix platform unittests.
Follow-up to 87db4ff1f4, which added
suppressions to unittests.status and a special case for Android to the
ThreadLocalStorageTest, both of which are unneccessary and should be
handled differently for the GTest based unittests.

87db4ff1f4 Fix/suppress unittests broken on Android
cctest/test-threads/ThreadJoinSelf is suppressed for Android, but the
test has since been moved to unittests/Thread.SelfJoin. Move the
suppression to unittests.status.

unittests/ThreadLocalStorageTest.DoTest fails on older Android devices
as it assumes the availability of more TLS slots than many devices
implement. Test a smaller number of slots (32) on Android. Remove old
suppression of test-platform-tls/FastTLS (which no longer exists).

cctest/test-mark-compact/RegressJoinThreadsOnIsolateDeinit can't deal
with shared mappings. Check for 's' instead of '-'.

8a00950303 [arm] Drop SMMLS support.
Apparently

 SMMLS r, b, c, a

computes

 r = ((a << 32) - b * c) >> 32

while the documentation is kinda misleading and states that it should
compute

 r = a - ((b * c) >> 32)

The actual behavior is kinda useless, so we drop the instruction again.

8617b3acf8 [turbofan] Fix HashCode/Equals for floating point operators.
Those floating point constant operators require bitwise handling of
their parameters, otherwise 0.0 equals -0.0. This is solved in a
general way by adding new base::bit_equal_to and base::bit_hash
function objects.

0a6e406927 Further improve hashing of pointers and integers.
Also make sure that the appropriate functions are inlined properly
(using V8_INLINE instead of inline to enforce it even with GCC),
and improve the HashIsOkish unittest.
