As QEMU supports the memory-less node, it is possible that there is
no RAM in the first numa node(also be called as node0). eg:
  ... \
  -m 128,slots=3,maxmem=1G \
  -numa node -numa node,mem=128M \

But, this makes it hard for QEMU to build a known-to-work ACPI SRAT
table. Only fixing it is not enough.

Add a testcase for this situation to make sure the ACPI table is
correct for guest.

Changelog:

This patch can pass the 'make check' in Peter's machine,
But, in my own and Eduardo's machine, we can pass it.

So I rebase and spilt it independently.

Peter:

could you help me test it in your machine.
then, give me the output files, such as /tmp/asl-6QYK7Y.dsl and /tmp/asl-1H1I7Y.dsl file.

As the failures reported by Peter were about the *.memhp test
case files, I think this patch is unlikely to be the cause of
those failures.  I believe the problem is at:

  From: Dou Liyang <douly.fnst@cn.fujitsu.com>
  Date: Fri, 1 Sep 2017 10:10:03 +0800
  Message-ID: <1504231805-30957-3-git-send-email-douly.fnst@cn.fujitsu.com>
  Subject: [PATCH v6 2/4] hw/acpi-build: Make assignment statement
           of next_base easy to read

However, I would still like to get test results from Peter before
applying this patch again.
