This changed in upstream change https://reviews.llvm.org/D98152 (aka
https://github.com/llvm/llvm-project/commit/a266af721153fab6452094207b09ed265ab0be7b)
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.

...because alignment is always nonzero.
This helps eliminate redundant runtime alignment checks, when a DST
is a field of a struct whose remaining fields have alignment 1.
