If we've truncated a wider read we can detect the condition earlier by
looking at the number of zeros we've read. So we don't trip up on
cases where we have written zeros to the start of the buffer we also
ensure we only start each offset read from the right address.

Expand the memory test to cover move of the softmmu code. Specifically
we:
- improve commentary
- add some helpers (for later BE support)
- reduce boiler plate into helpers
- add signed reads at various sizes/offsets
- required -DCHECK_UNALIGNED

There is nothing inherently architecture specific about the memory
test although we may have to manage different restrictions of
unaligned access across architectures.

This is not really i386 only, we can have the same test for all
architectures supporting system tests.

We can certainly support some common tests for system emulation that
make use of our minimal defined boot.S support. It will still be up to
individual architectures to ensure they build so we provide a
MULTIARCH_TESTS variable that they can tack onto TESTS themselves.
