* cranelift-native: Move riscv to separate module
* cranelift-native: Read /proc/cpuinfo to parse RISC-V extensions
* ci: Add QEMU cpuinfo emulation patch
This patch emulates the /proc/cpuinfo interface for RISC-V. This
allows us to do feature detection for the RISC-V backend.
It has been queued for QEMU 8.1 so we should remove it as soon as
that is available.
