Describe the issue:

Tests were conducted using solc versions 0.8.27 and 0.8.28, and both failed to generate IR. The bug persists in the latest release. Code:

contract Test {
  function test() private returns(uint8) {
    return (type(uint8)).max;
  }
}

Run slither: slither a.sol

Output:

ERROR:SlitherSolcParsing:
