0d8ea24351 Added a workaround for clang UBSAN failures. 
Clang UBSAN considers an UB subtracting from a null pointer, which is
required for one of the tests. Disable that test when UBSAN is enabled.

e8ccfce2dc Added check for BOOST_NO_ALIGNMENT for float128 tests. 
Atomic storage can be implemented without int128 support but when
explicit alignment specification is supported.

c043562511 Disable floating point tests when BOOST_ATOMIC_NO_FLOATING_POINT is defined. 
Also check that int128 is available for float128 tests. Int128 is used
as the storage for atomic variables.

ffad580fcf Working around CI failures for clang. 
Downgraded clang builds to Xenial since there are no 32-bit packages for Bionic.
Disabled 32-bit clang UBSAN builds due to linking errors.

1dd9dd831b [CMake] Add minimal cmake file 
Generate cmake target that builds the library and which can
be used by other libraries to express their dependency on
this library and retrieve any configuration information
such as the include directory, binary to link to,
transitive dependencies, necessary compiler options or the
required C++ standards level.

b092a25923 Revert "Added an experimental partial CMakeLists.txt for dependency tracking in CMake projects." 
This reverts commit 5ad28ffd18.

Apparently, just adding include paths to user's CMake projects is not enough
for the original requester.

6e14ca24da Removed clang-specific branch for x86 DCAS-based loads. 
The storage to load from is const-qualified and DCAS via compiler intrinsics
require an unqualified pointer. Use asm implementation instead, which should be
as efficient as intrinsics, if not better, in this case.

Fixes https://github.com/boostorg/atomic/issues/15.

406228d493 Made initializing constructor of atomic<> implicit. 
This is an attempt to make boost::atomic<> interface closer to the standard. It
makes a difference in C++17 as it mandates copy elision, which makes this code
possible:

  boost::atomic<int> a = 10;

It also makes is_convertible<T, boost::atomic<T>> return true, which has
implications on the standard library components, such as std::pair.

This removes the workaround for gcc 4.7, which complains that
operator=(value_arg_type) is considered ambiguous with operator=(atomic const&)
in assignment expressions, even though conversion to atomic<> is less preferred
than conversion to value_arg_type. We try to work around the problem from the
operator= side.

Added a new compile test to check that the initializing constructor is implicit.

095812d84f Make the default constructor trivial if the user's type default constructor is. 
This requires the is_trivially_default_constructible type trait, which is not
available in the older libstdc++ versions up to gcc 5.1. Thus the config macro
is updated to reflect the fact that Boost.Atomic now has more advanced needs.

Also, attempt to work around Intel compiler problem, which seems to break
(allegedly) because of the noexcept specifiers in the defaulted default
constructors. This may not be the cause, so this change will need to be tested.

Also, use value_arg_type consistently across different specializations of
basic_atomic.
