Problem with stacktraces and optimized code in Solidity 0.8.x

[haltman-at]

Issue

See this Brownie PR; we're also going to need a fix for this.

Basically, with Solidity 0.8.x, if optimization is turned on, all reverts will appear to be the same revert, which may mess up stacktraces. So, we may want something where in this case we effectively treat that code that maps to reverts as unmapped instead...?

Environment

• Truffle version (truffle version): 5.1.67
