It's expected that this has memory leaks, there's no clean shutdown in the CLI right now.
This commit fixes some more fallout found on oss-fuzz about the x64 generating rounding builtins when it shouldn't be. This situation is caused by simd float rounding instructions which the x64 backend lowers to libcall-per-element and now needs to move that logic to the frontend instead.
This commit is similar to bytecodealliance#10699, another instance of a libcall popping up late in the x64 backend. Fuzzing found this issue and to help verify this is the last one I've run the whole `*.wast` test suite with the x86_64 baseline (no target features) and saw the panic before this PR and no more panics after.
…#10739) The public function `generated_files` in `cranelift-assembler-x64` makes the generated `rlib` non-deterministic because it contains the full paths of generated files. But this function is only used in `main.rs` of the same crate, so this change inlines it there to keep the library artifact deterministic while maintaining the same behavior.
