Line find

[JonathanxD]

CodeAPI-BytecodeWriter provides a way to generate line numbers based on CodeSource index. To help to find out the CodePart that causes the error, we should provide a findLine utility method for CodeSource.

Usage example:

val codeSource = CodeAPI.sourceOfParts(
  a, // 0
  b, // 1
  CodeAPI.sourceOfParts(
    c, // 2
    d // 3
  )
)


CodeSourceUtil.findLine(3, codeSource) // d
