gcc46-pr46626.patch
Untested fix. The problem seems to be that the B::B() ctor body, which is
constexpr (and g++ generated) has a CLEANUP_STMT in it, and
build_data_member_initialization ignores CLEANUP_STMT, which means the setting
of vtable pointer to _ZTV1B + 16 is ignored, thus it stays to be _ZTV1A + 16.
The attached patch handles CLEANUP_BODY of CLEANUP_STMT by recursing into it.
