Title:
  "accel/tcg: demacro cputlb" break qemu-system-x86_64 on 32-bit x86
  host

Status in QEMU:
  In Progress

Bug description:
  As described in https://lists.gnu.org/archive/html/qemu-
  devel//2019-05/msg07362.html I run into TCG regression in qemu-git.

  Unfortunately, fix from bug
  https://bugs.launchpad.net/qemu/+bug/1830872 seems to be nonn-
  effective for my case.

  For reproduction (on 32-bit x86 host, in my case Slackware with gcc
  5.5.0):

  ./configure --target-list=x86_64-softmmu --disable-werror --enable-
  debug-tcg

  make (-j5 in my case)

  try to boot any 64-bit kernel:

  x86_64-softmmu/qemu-system-x86_64 -kernel /boot/bzImage-4.12.0-x64
  -accel tcg

  result is - qemu appear to hang right after "Booting the kernel" line.
  Decompression (xz) was ok.

  Tested with qemu-git commit  e2a58ff493a2e00db3e963c1839c5374500110f2

  32-bit OS can be booted fine, and -enable-kvm also allow 64 bit
  kernel/os to boot.
