Rollup merge of rust-lang#72977 - tblah:riscv-codegen-llvm10, r=nikom…

…atsakis Fix codegen tests for RISC-V Some codegen tests didn't seem relevant (e.g. unsupported annotations). The RISC-V abi tests were broken by LLVM 10, c872dcf fixes that (cc: @msizanoen1) I'm not sure about skipping catch-unwind.rs and included that change here mostly as a request for comment - I can't tell if that's a bug.
