While the compilers will generally happily synthesise a 64 bit value
for you on 32 bit systems it doesn't exercise anything on QEMU. It
also makes it hard to accurately compare the accesses to test_data
when instrumenting.

This is useful information when debugging memory issues so lets
improve by:
- include the ptr address for u8 fills (like the others)
- indicate the number of operations for reads and writes
- explicitly note when we are flushing
- move the fill printf to after the reset

Store the bytes in descending order on big-endian.
Invert the logic in the multi-byte signed tests on big-endian.
Make the checks in the multi-byte signed tests stricter.

System emulation tests do not run in a hosted environment, since they
do not link with libc. They should only use freestanding headers
(float.h, limits.h, stdarg.h, stddef.h, stdbool.h, stdint.h,
stdalign.h, stdnoreturn.h) and should be compiled with -ffreestanding
in order to use the compiler implementation of those headers
rather than the one in libc.
Some tests are using inttypes.h instead of stdint.h, so fix that.

As per POSIX specification of limits.h [1], OS libc may define
PAGE_SIZE in limits.h.
Self defined PAGE_SIZE is frequently used in tests, to prevent
collosion of definition, we give PAGE_SIZE definitons reasonable
prefixs.

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.
