[llvm] ea31a17 - [AArch64] Fix -Wunused-variable in -DLLVM_ENABLE_ASSERTIONS=off builds

[David Blaikie via llvm-commits]

Not sure if this is better than the traditional void casts?

But if it is, maybe we should have a style guide discussion/authoritative
suggestion about it? (& probably the sort of thing where a mass cleanup
wouldn't be too bad - not sure anyone would much care about the blame lines
on the existing void casts... )
