We're not actually testing for alignment, we just want to know that whatever incoming alignment got propagated. Do that by capturing the alignment and checking that it's actually what's passed later, instead of hard-coding an alignment value.

It turns out that the AVX bots have different alignment for their vectors, and my test mistakenly assumed a particular vector alignent on the stack. Instead, capture the alignment and test for it in subsequent operations.

Summary:
r337887 started using memset for automatic variable initialization where sensible. A follow-up discussion leads me to believe that we should better test automatic variable initialization, and that there are probably follow-up patches in clang and LLVM to improve codegen. It’ll be important to measure -O0 compile time, and figure out which transforms should be in the frontend versus the backend.
This patch is just a test of the current behavior, no questions asked. Follow-up patches will tune the code generation.
