This adds support for the [Sail
language](https://github.com/rems-project/sail) - a DSL for defining
ISAs.
It's not quite ready but I need some help. These are the main remaining
issues:
1. When you "link to binary" it does disassemble the binary properly,
but the syntax highlighting and line numbers are broken.
2. If you try to execute the code without a `function main() -> unit =
...` then it gives this error in the compiler output:
```
Internal Compiler Explorer error: Error: spawn /tmp/compiler-explorer-compiler2025025-31052-c8gern.pf8t/model.c EACCES
at ChildProcess._handle.onexit (node:internal/child_process:285:19)
at onErrorNT (node:internal/child_process:483:16)
at process.processTicksAndRejections (node:internal/process/task_queues:82:21)
Compiler returned: -1
```
This is weird - it should give a linker with an undefined reference to
`zmain`.
3. Sail compiles to C, and then I added extra steps to compile that to
binary (if you select `Execute the code`), but as you can see I had to
move the binary back over the C file, so in this case `model.c` is
actually an ELF file. It works but that seems very weird. There is a
`getExecutableFilename()` method I could override, but doing that seems
to make it even more confused.
4. I also had to have a fake flag for `binary` because the `filters`
don't seem to get set correctly when passed to `runCompiler()`. E.g.
`buildExecutable()` doesn't pass them at all. Not sure what is going on
there. Seems to work though.
Any help appreciated!
PS: Sail is a cool language. It has lightweight dependent type for
integers and bit vectors, which I haven't demonstrated in the examples
yet, but they're neat.
