Fix to allow 32-bit Valgrind to run on AMD64 boxes. Note: this does

NOT allow Valgrind to work with 64-bit executables - only with 32-bit
executables on an AMD64 box.

VG_(valgrind_end) now has a slightly different meaning to all the other
VG_(*_end) vars -- ie. it names the last byte, whereas the others go
one byte past the end.
