Enable compile-time enforcement that absl::Substitute patterns to not contain unescaped $ symbols.
absl::Substitute already considers unescaped $ symbols undefined behavior and crashes when it's passed them in debug builds. Some code isn't ever built in debug mode, though, and inadvertently used some unescaped $ symbols, which led to surprising results. This change will prevent that problem from happening in the future.

This CL introduces following changes to the class FlagImpl:
* We eliminate the CommandLineFlagLocks struct. Instead callback guard and callback function are combined into a single CallbackData struct, while primary data lock is stored separately.
* CallbackData member of class FlagImpl is initially set to be nullptr and is only allocated and initialized when a flag's callback is being set. For most flags we do not pay for the extra space and extra absl::Mutex now.
* Primary data guard is stored in data_guard_ data member. This is a properly aligned character buffer of necessary size. During initialization of the flag we construct absl::Mutex in this space using placement new call.
* We now avoid extra value copy after successful attempt to parse value out of string. Instead we swap flag's current value with tentative value we just produced.

Set correct flags for clang-cl.
https://github.com/abseil/abseil-cpp/pull/278
clang-cl produce binaries with MSVC ABI and wants to be as
flag-compatible with pure MSVC as possible, so this leads to all sorts
of weird cases.
clang-cl alias /Wall as clang's -Weverything which is way too verbose,
so it needs /W3 like pure MSVC.
clang-cl only understand GCC style warning flags (-W[no]blah) and just
silent drop MSVC style warning flags (/wd[num]).
clang-cl needs MSVC define flags since it is consuming the same header
files as pure MSVC.
CMake set CMAKE_CXX_COMPILER_ID as Clang when clang-cl is detected, so
need extra if (MSVC) to differentiate it.
We are not doing clang-cl specialization in Bazel as currently there
is no reliable way to detect clang-cl in Bazel..
Other changes:
Add ABSL_ prefix to variable names to avoid name collision in CMake.

Only recording the probe length on insertion causes a huge overestimation of

With natural growth, elements are inserted when the load factor is between

actually inserted when the load factor is less than max/2 and have a much lower
average probe length.

Fix ABSL_HAVE_THREAD_LOCAL when compiling for iOS 8 with Xcode 10.
Xcode 10 has moved the check for thread_local to a link time, so
clang reports __has_feature(cxx_thread_local) but then linking fails
with messages like this:
ld: targeted OS version does not support use of thread local variables

Make the absl::c_set_xxxx() algorithms refuse to compile when passed an unordered collection from std:: or absl::.
These algorithms operate on sorted sequences; passing an unordered container to them is nearly certainly a bug. This change is technically an API break, but it only breaks incorrect code.
We could try to be more clever and detect unordered collections from other libraries, but false positives will break legal code, and this would constitute an API break Abseil cannot afford.

MSVC 2017's STL throws a Structured Exception (not a C++ exception, essentially equivalent to SIGSEGV) when variant::emplace calls a throwing constructor when using the debug multithreaded MSVC runtime DLL. This manifests in dbg mode in Bazel builds. Disable tests which trigger this bug.
It's impossible to specifically pull out MSVC 2017 -dbg modes because there's no way for Bazel to know when version of MSVC is being used -- you tell Bazel the directory where the MSVC tools live, not which version of MSVC tools to use. Thus the best we can do is switch on _DEBUG, which is set whenever the debug runtime is selected with the /MDd build flag, as in Bazel -dbg modes. See https://msdn.microsoft.com/en-us/library/b0084kay.aspx ctrl-f "_DEBUG"

absl: fix backoff logic in SpinLockWait
There are 3 bugs in loop variable handling:
1. It starts with 0, but AbslInternalSpinLockDelay ignores loop == 0.
So it does not actually wait when it should.
2. loop is incremented after successful state changes,
but it should not (why would be increase backoff delay after that?).
3. loop is incremented after CAS failures,
but it should not (why would be increase backoff delay after that?).
Use the same handling of loop as used in SpinLock.
