listing: add -L option for additional listing info
Add an -L option for additional listing information. Currently supported is -Le, which emits each line after processing through the preprocessor, and -Lm, which displays each single-line macro defined or undefined. NASM doesn't preserve the names of unused arguments, nor does it have any technical reason to do so. Instead of adding complexity to save them, make unnamed parameters official by specifying an empty string in the argument list. This has the additional advantage that () is now simply considered a single empty argument, which means that NASM should now properly handle things like: %define myreg() eax mov edx,myreg() ... similar to how the C preprocessor allows an empty macro argument list which is distinct from a macro with no arguments whatsoever.
