tests: accept llvm intrinsic in align-checking test 

This changed in upstream change https://reviews.llvm.org/D98152 (aka
a266af7211)
wherein LLVM got smarter about using intrinsics. As best I can tell the
change I've made here preserves the intent of the test on LLVM 14 and
before while also passing on LLVM 15 and later.
