Spiderwasm on 32-bit x86 always uses a 16-byte-aligned stack pointer. Change the setting for the "native" convention as well, for compatibility with Linux and Darwin ABIs, and so that if a platform has different ABI rules, the problem will be detected in code emitted by Cretonne, rather than somewhere else.
This crate contains the core Cretonne code generator. It translates code from an intermediate language into executable machine code.
