c75d7a685d src: major cleanups, introduce new eXtended Span class 
- initial minimally invasive eXtended Span implementation
- rename ptr_diff to ptr_diff_bytes
- move some files to util subdir
- lots of cleanups
- start using the new checked pointers - this needs some real-world testing

252143d0bb WIP: smallest executable on Apple M1 (aarch64 or arm64) 
Requirements for success after snipping a loader_command:
    "codesign -s - my_app" must succeed.
    "lldb my_app; process launch -s; continue" must succeed.

Optional loader_commands (macho-snip can remove these successfully):
    LC_UUID, LC_BUILD_VERSION, LC_SOURCE_VERISON,
    LC_DATA_IN_CODE (when 0==datasize)

Apple "strip -N" clears out LC_SYMTAB and LC_DYSYMTAB, but leaves
LC_DYLD_INFO_ONLY.export_size.  Perhaps this could be zero if
constructed that way; snipping seems tedious because codesign
requires that __LINKEDIT must have no gaps.

LC_FUNCTION_STARTS seems to be required by codesign.
codesign wants offsets that point into __LINKEDIT to be in order:
    LC_DYLD_INFO_ONLY, LC_FUNCTION_STARTS, LC_DATA_IN_CODE, LC_SYMTAB

MacOS seesm to require LC_LOAD_DYLINKER (else "zsh: Kiled"),
which seems to require LD_LOAD_DYLIB (else SIGABRT).
