The changes in src/exception.cpp and cmake/Modules/HandleLibCXXABI.cmake fix a
bug when building libc++ with GCC. Because GCC does not support __has_include
we need to explicitly tell it that we are building against libc++abi via the
preprocessor definition `LIBCXX_BUILDING_LIBCXXABI`.

The changes in include/ratio are to work around CWG defect
1712 (constexpr variable template declarations). GCC 4.8 and before has not
adopted the resolution to this defect.

The changes in include/exception work around an issue where is_final is used
without it being defined in type_traits.

[RewriteStatepointsForGC] For some values (like gep's and bitcasts) it's cheaper to clone them after statepoint than to emit proper relocates for them. This change implements this logic. There is alredy similar optimization in CodeGenPrepare, but doing so during RewriteStatepointsForGC allows to capture more opprtunities such as relocates in loops and longer instruction chains.
