* Use `global_asm!` instead of external assembly files This commit moves the external assembly files of the `wasmtime-fiber` crate into `global_asm!` blocks defined in Rust. The motivation for doing this is not very strong at this time, but the points in favor of this are: * One less tool needed to cross-compile Wasmtime. A linker is still needed but perhaps one day that will improve as well. * A "modern" assembler, built-in to LLVM, is used instead of whatever appears on the system. The first point hasn't really cropped up that much and typically getting an assembler is just as hard as getting a linker nowadays. The second point though has us using `hint #xx` in aarch64 assembly instead of the actual instructions for assembler compatibility, and I believe that's no longer necessary because the LLVM assembler supports the modern instruction names. The translation of the x86/x86_64 assembly has been done to Intel syntax as well as opposed to the old AT&T syntax since that's Rust's default. Additionally s390x still remains in an external assembler file because `global_asm!` is still unstable in Rust on that platform. * Simplify alignment specification * Temporarily disable fail-fast * Add `.cfi_def_cfa_offset 0` to fix CI * Turn off fail-fast * Review comments
