Previously the test's targets were restricted to avoid the AIX target, but
it should be marked unsupported for system-aix instead because the test
fails to run on AIX as well.
Previous attempt to restrict this test to x86 and aarch64 targets only didn't work.
So XFAIL this test while investigating to get the AIX bot back to green.
See https://reviews.llvm.org/D140867.
The signature of the constructor/destrucor of the global variables is
different in different targets. And the CHECKs in the test is
unavailable in other targets (e.g., AIX). So the patch tries to avoid
the test failure by requiring the target type.
Closes https://github.com/llvm/llvm-project/issues/59765.
Currently we will generate the global ctor/dtor for variables in
importing modules. It will cause multiple initialization/destructions.
It makes no sense. This patch tries to not generate global ctor/dtor for
variables which are available externally. Note that the variables in
header units and clang modules won't be available externally by default.
