Regression caught by replay_kernel.py:ReplayKernelNormal.test_aarch64_virt

[Cleber Rosa <crosa@redhat.com>]

Hi everyone,

tests/acceptance/replay_kernel.py:ReplayKernelNormal.test_aarch64_virt
is currently failing consistently (first found that in [1]).

I've bisected it down to the following commit:

78ff82bb1b67c0d79113688e4b3427fc99cab9d4 is the first bad commit
commit 78ff82bb1b67c0d79113688e4b3427fc99cab9d4
Author: Richard Henderson <richard.henderson@linaro.org>

    accel/tcg: Reduce CF_COUNT_MASK to match TCG_MAX_INSNS
    
    The space reserved for CF_COUNT_MASK was overly large.
    Reduce to free up cflags bits and eliminate an extra test.

To reproduce it:

1. configure --target-list=aarch64-softmmu
2. meson compile
3. make check-venv
4. ./tests/venv/bin/avocado --show=test run tests/acceptance/replay_kernel.py:ReplayKernelNormal.test_aarch64_virt

PS: I haven't had the time yet to scan the mailing list for possible
discussions about it.
