issue-44056.rs was incorrectly moved to compile pass and should not if hardware does not support AVX

[gnzlbg]

See #55667.

There are two problems:

• the issue-44056.rs test was incorrectly moved from run-pass (Compiled executable fails to launch when built with AVX and LTO enabled #44056) to compile-pass: this test must be executed

• the issue-44056.rs test should not run on non-AVX hardware, and this cannot be checked in the test itself. That is, the test runner has to detect whether the host supports AVX, and then and only then, attempt to run the test.

the issue-44056.rs test should not run on non-AVX hardware, and this cannot be checked in the test itself. That is, the test runner has to detect whether the host supports AVX, and then and only then, attempt to run the test.

Alternatively, the actual test could be in an auxiliary file that is executed by the main test via std::process. There are some other tests that do this, e.g. for a test that aborts the process to check that the right signal is raised.
