Release v1.11 causes rustc compiler to fail with inline assembly #342

See https://github.com/axiom-crypto/snark-verifier/issues/43 for a cargo bisect.

In short, for very unknown reasons, the change from ruint v1.10 -> v1.11 has caused something to change in how the recent rustc compilers / LLVM optimizes raw assembly code blocks in https://github.com/axiom-crypto/halo2curves/blob/main/src/bn256/assembly.rs

I have no idea what could have caused this, so would be interested in learning.
