[NFC] Fix a test faliing in AIX

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.

+// FIXME: Since the signature of the constructors/destructors is
+// different in different targets. The current CHECK can't work
+// well for other targets like AIX. So here is the REQUIRES.
+// It would be better to add the corresponding test for other test.
+// REQUIRES: x86-registered-target,aarch64-registered-target
