LibX86+disasm: Use an output format closer to objdump

This mainly does two things,
1. Removes spaces after commas
2. Elides "0x" and leading zeros in most contexts

Remaining differences are:
1. objdump always has memory size annotations
   We lack these and probably have some annotations wrong
2. Boolean check names
   We use jump-zero, while objdump uses jump-equal for example
3. We sometimes add "00 00" symbols, which objdump elides
4. We always demangle (This is a good thing)
5. We always resolve relocations (This is a good thing)
6. We seem to detect some symbols differently/incorrectly
