Because sa may be 0,

may attempt a zero-width deposit at bit 32, which will assert
for TARGET_REGISTER_BITS == 32.

Use the newer extract2 when possible, which itself includes the
rotri special case; otherwise mirror the code from trans_shrpw_sar,
using concat and shri.

"meson test" starting with version 0.57 is just as capable and easy to
use as QEMU's own TAP driver.  All existing options for "make check"
work.  The only required code change involves how to mark "slow" tests;
they need to belong to an additional "slow" suite.

The rules for .tap output are replaced by JUnit XML; GitLab is able
to parse that output and present it in the CI pipeline report.

Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

Add -j <JOBS> parameter, to run tests in several jobs simultaneously.
For realization - simply utilize multiprocessing.Pool class.

Notes:

1. Of course, tests can't run simultaneously in same TEST_DIR. So,
   use subdirectories TEST_DIR/testname/ and SOCK_DIR/testname/
   instead of simply TEST_DIR and SOCK_DIR

2. multiprocessing.Pool.starmap function doesn't support passing
   context managers, so we can't simply pass "self". Happily, we need
   self only for read-only access, and it just works if it is defined
   in global space. So, add a temporary link TestRunner.shared_self
   during run_tests().

g_test_rand_int() must not be called before g_test_init(), otherwise

These filter tests need a NIC, no matter which one, so they use a common
NIC by default. However, these common NIC models might not always have
been compiled into the QEMU target binary, so assuming that a certain NIC
is available is a bad idea. Since the exact type of NIC does not really
matter for these tests, let's switch to "-nic" instead of "-netdev" so
that QEMU can simply pick a default NIC for us.
This way we can now run the tests on other targets that have a default
machine with an on-board/default NIC, too.

Example output of `uname -a` on an initial Gentoo LA64 port, running
the upstream submission version of Linux (with some very minor patches
not influencing output here):

And the same on the vendor-supplied Loongnix 20 system, with an early
in-house port of Linux, and using the old-world ABI:
