Hm, I'm not quite sure about this.  I think there's a risk that this
will let Valgrind allocate a mapping in the last 64k of the address
space, which would be bad.

The trouble here is obviously the 4G wrap-around, and that the end
address is outside the range.  I guess you could put ROUNDUP(argc_addr,
0x10000)-1, but I'm not quite sure what happens if VG_(valgrind_end)
isn't page-aligned.
