Work around clang-cl issue with MSVC's safeint.h for now
At least some C:\Program Files (x86)\Windows Kits\10\Include\10.0.10240.0\ucrt\ safeint_internal.h, in the specialization of LargeIntRegMultiply::RegMultiply for signed __int64, contains an (unnecessary) C-style cast from l-value unsigned __int64 tmp RegMultiply( ..., ..., (unsigned _int64)tmp ) == SafeIntNoError ) which clang-cl correctly identifies as producing a prvalue (so cannot bind to the third 'unsigned __int64& ret' parameter of that RegMultiply call), while MSVC apparently has a non-standard mis-feature of treating such a "self-cast" as an lvalue. Until clang-cl learns about that mis-feature too, use the fallback implementation of o3tl/safeint.hxx when compiling with clang-cl.
