Only what was reported for the RC:
1. For x86 and x64: std::alignment_of<std::nullptr_t>::value is 1, yet
compiler aligns at 4
2. For x86: std::alignment_of<T Class::*>::value is 4, yet compiler aligns at 8
    For x64: std::alignment_of<T Class::*>::value is 8, yet compiler aligns at 4
3. For x86: std::alignment_of<T (Class::*)()>::value is 4, yet
compiler aligns at 8
    For x64: std::alignment_of<T (Class::*)()>::value is 8, yet
compiler aligns at 4

I haven't checked the RTM yet, but apparently VC12's std::alignment_of
for the relevant types reported the same value that the compiler chose
to align objects of those types.
