Run the state machine to generate line number matrix
Line number informations generated by the compiler are stored in the .debug_line section. Conceptually, they can be seen as a large matrix, with row such as "file", "line", "column", "is_statement", etc... However such a matrix would be too big to store in an object file, so DWARF instead generate this matrix using bytecode fed to a state machine.
Note
Each compilation unit can have its own line number program.
