Solidity compilation broken for solc0.8.0

[sinasab]

Environment information

• brownie Version: v1.12.2
• ganache-cli Version: 6.12.1
• solc Version: 0.8.0
• Python Version: 3.8
• OS: osx/linux/win

What was wrong?

I think brownie's solidity compatibility may be broken for solidity version 0.8.0.

To reproduce, create a solidity contract and try to compile it with solc 0.8.0 via brownie compile. Here's a minimal contract I was able to reproduce with:

pragma solidity 0.8.0;

contract Testy {
    address public testAddress;
    constructor() public {}
}

when I try to run brownie compile --all, I get this error:

How can it be fixed?

By changing the solidity version to something else. For example, when I change the solidity version in the file to something like 0.6.0, it appears to compile without issue.

From my brief tinkering, it looks like 0.8.0 is the first version that this breaks (ie. it compiles fine on 0.7.6).

This appears to be the same bug as #890, there is a fix in #895 but the CI is showing other, unrelated issues with 0.8.0 that still need addressing 😬

Thanks for the minimal example, it will be useful for writing some tests around this.
