Minor work related to removing the assumption that value initialization
implies an all-zero bit pattern.

// Otherwise, just memset the whole thing to zero. This is legal
// because in LLVM, all default initializers are guaranteed to have a
// bit pattern of all zeros.
+ // FIXME: That isn't true for member pointers!
// There's a potential optimization opportunity in combining
// memsets; that would be easy for arrays, but relatively
// difficult for structures with the current code.
