077793fa5e Update pefile.cpp 
I found a bug by participating to the Binary Golf Grand Prix 3 (https://tmpout.sh/bggp/3/) : upx text.exe segfaults when NumberOfSections in the IMAGE_FILE_HEADER is NULL, so 
if (memcmp(isection[0].name,"UPX",3) == 0) triggers a NULL pointer dereference causing a crash.
To fix it, just have to check if isection is NULL (which means NumberOfSections = 0) or not.

717150b7f3 Stupid MSVC: bad C4706: assignment within conditional expression 
-    for (unsigned j=0; (k = dt_names[j]); ++j) {
+    for (unsigned j=0; ((k = dt_names[j]), k); ++j) {

The complaint was:
    p_lx_elf.cpp(5710) : warning C4706: assignment within conditional expression
which is INCORRECT, as shown in the change which is 100% equivalent.
The assignment occurs BEFORE the conditional expression.

GNU_HASH table when there is no ElfXX_Shdr for it.  64-bit only for now.

e7ca5c54ff Fix --brute for p_lx_elf.cpp, which compresses multiple pieces 
Force all pieces to use the same de-compressor.
(Future: allow each PT_LOAD to choose its own.)
Has minor wobbles due to page alignment, and size of de-compressor.

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).
