[Trivial] tweak flat_hash_map.h doc comment

The comment is probably right both ways, but the lack of an "if" here seemed jarring to me.

16bc03b9b30fbf08d7dc61025fa8ec4b57077be8 by Abseil Team <absl-team@google.com>:

Fix symbolization for elf files whose SYMTAB section is stripped, but have a DYNSYM section.

Previously, if we did not find a SYMTAB section, we would bail out of symbolization early, rather than checking the DYNSYM section.

Use a typedef to allow building with NVCC

Without this change NVCC fails to compile compressed_tuple.h.  NVCC is relevant
because TensorFlow uses NVCC on Ubuntu and inclues abseil.

Updates the ScopedAllocatorWorks test for InlinedVector to not rely on the byte count allocated by the standard library

In doing so, removes LegacyNextCapacityFrom(...) impl function from InlinedVector

Also applies clang-format to the test file

efc5b9c221ee31e15d10b35d31c8f3ae6eddaa8c by Abseil Team <absl-team@google.com>:

Follow CCTZ's lead and allow GetWeekday() and GetYearDay() to be
called with any civil-time type.  A CivilSecond, for example, has
a weekday just as much as a CivilDay does.

Increase the timeout of randen_engine_test.
It seems to timeout under TSAN often enough to justify the increase.
