feat: unary operators

[wackbyte]

I think I've gotten codegen done, but it seems that the type of expressions with unary operators is, for whatever reason, unknown.

Seems to be because this is left unimplemented:

mun/crates/mun_hir/src/ty/infer.rs

Line 403 in 39babc4

Expr::UnaryOp { .. } => Ty::Unknown,

Looks like CI failed due to a network error.

[wackbyte]

It looks like not is actually implemented for integers in Rust, so I'll go ahead and add that.

I checked master, but the mun_abi/c submodule is currently set to b437e21. You updated it to the commit of @baszalmstra's WIP array support, but since that is not in master yet, the abi should not be updated to that commit yet.

[baszalmstra]

Yes! I approved it!

However, there appears to be a merge conflict. Can you rebase this branch on master?

[wackbyte]

Sorry about this, but I (still) don't know how to rebase. Can you give me some steps on doing that?

[baszalmstra]

Sure, does this help: https://github.com/edx/edx-platform/wiki/How-to-Rebase-a-Pull-Request

Squashing your changes is not necessary.
