Solang crashes when the code contains specific inline assembly.

[lum7na]

Hello! When I tried to compile the following code using solang, I encountered an error that caused the compiler to crash.

contract Test {
  uint8 constant A = 0;a
  function test(string memory str) public returns(uint8) {

    assembly  {
      for { let b := 0 } lt(b, 0x60) { b := add(b, 0x20) } { continue }
    }
    return A;
  }
}

thread 'main' panicked at src/codegen/dead_storage.rs:370:16:
index out of bounds: the len is 0 but the index is 0
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

I didn't add any special compilation parameters. My compilation command was solang compile a.sol --target solana. The version of solang I used is v0.3.3.
