Luqman Aden 2b66aeed20 Preserve nonnull metadata on Loads through SROA & mem2reg. ...

Summary:
https://llvm.org/bugs/show_bug.cgi?id=31142 :

SROA was dropping the nonnull metadata on loads from allocas that got optimized out. This patch simply preserves nonnull metadata on loads through SROA and mem2reg.
