Rollup merge of #91424 - richkadel:llvm-patch-instrproferror, r=tmandry
Update LLVM with patches for better llvm-cov diagnostics

These patches to LLVM were added to help debug occasional errors that
cause coverage reporting to fail. Prior to this patch, the only messaging
was that the coverage data was malformed. Hopefully the improved
messaging will help identify the root cause of these errors, when they
arise, so we can make corrections to coverage output from Rust.
