tests/tcg: add a system test to check memory instrumentation

At first I thought I could compile the user-mode test for system mode
however we already have a fairly comprehensive test case for system
mode in "memory" so lets use that.

As tracking every access will quickly build up with "print-access" we
add a new mode to track groups of reads and writes to regions. Because
the test_data is 16k aligned we can be sure all accesses to it are
ones we can count.

First we extend the test to report where the test_data region is. Then
we expand the pdot() function to track the total number of reads and
writes to the region. We have to add some addition pdot() calls to
take into account multiple reads/writes in the test loops.

Finally we add a python script to integrate the data from the plugin
and the output of the test and validate they both agree on the total
counts. As some boot codes clear the bss we also add a flag to add a
regions worth of writes to the expected total.

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.

tests/tcg: compile system emulation tests as freestanding

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.

tests/tcg: better detect truncated reads

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.
