llvm9: add fixes for the powerpc backend (prepare for rust 1.39 switch to llvm9)
This fixes Rust with llvm9 on ppc32, so that we can finally switch to it (`llvm-006-bigpic.patch`) - previously it would emit wrong executables that segfault.

While at it, I'm adding an upstream backport that fixes incorrect codegen for certain things such as Chromium.

A patch file from https://github.com/void-linux/void-packages/pull/16132.patch is attached
