Solang fails to properly handle the not implemented exception.

[lum7na]

When the program contains unimplemented syntax, Solang crashes directly instead of generating an error message.

solang compile a.sol --target solana

contract Test {
  function test(int256 a, int256 b) public returns(int256) {
    assembly  {
      {
        selfdestruct(0x0)
      }
    }
    return a;
  }
}

Output:

thread 'main' panicked at src/emit/solana/target.rs:1668:9:
not implemented
