In the PPC32 SVR4 ABI, a va_list has copies of registers from the
function call. va_arg looked in the wrong registers for (the pointer
representation of) an object in Objective-C, and for some types in
C++. Fix va_arg to look in the general-purpose registers, not the
floating-point registers. Also fix va_arg for some C++ types, like a
member function pointer, that are aggregates for the ABI.
Anthony Richardby found the problem in Objective-C. Eli Friedman
suggested part of this fix.
