13 years agoconstexpr: Disable checking of constructor member initializer lists for

constexpr: Disable checking of constructor member initializer lists for
constexpr constructor templates. Such checking is optional, and currently hard
to get right since clang doesn't generate implicit member initializers until
instantiation (even for non-dependent members).

This is needed for clang to accept libstdc++ from g++4.6 in c++0x mode.

of this, a conformance test was removed on the basis that this is almost
certainly a defect as with most of union initialization. As it is, clang
