[libre-riscv-dev] SPIR-V parser completed except for tests

[Jacob Lifshay]

Discovered why:
You're using an older version of Rust that can't deduce that those
particular writeln calls can't fail (Rust crashes or panics on
out-of-memory instead of reporting an error through Result::Err).

It stops warning at rustc version 1.28.0
