Bug#907622: llvm-toolchain-6.0: Please backport patch to fix miscompiled code (alignment)

Hi!

LLVM has a bug in its SROA implementation which can cause
the generated code to contain unaligned accesses. This
was fixed in [1], the corresponding Rust issue is [2].

Can you backport the fix? It affects all architectures, not
just sparc64. It's just that the compiled binaries crash
immediately on sparc64 while on other architectures the
incorrect behavior might be more subtle.

Thanks,
Adrian
