Nicholas Nethercote 782dd25de9 64-bit cleanness: fix nasty bug... in the memory allocators, redzones ...

were being kept as UInts.  They were sometimes negated and then used as
indices to arrays, and on 64-bit platforms they get converted
incorrectly (using zero-extension instead of sign extension, I think)
before the indexing happens, giving a totally bogus index.

The fix was to convert all these types to SizeT.  It would be nice to be
able to avoid this automatically somehow in the future.
