adb0ca8250 Many changes for ELF shared libraries on Linux and Android 
Handling more than 2 PT_LOAD (and thus more than 1 executable PT_LOAD)
required extensive changes.  But the bonus is the infrastructure
to support a different (de-)compression algorithm for each PT_LOAD.

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).
