Create ELF aliases for identical symbols This change greatly reduces the number of modules that need to be compiled. The only issue right now is that sometimes when viewing symbol table entries, the aliased symbol is chosen.

Clean up more code - Found some bugs in LLVM compiler-rt library - The useless LIBC_STUBS package is now deleted - Improve the overflow checking story even further - Get chibicc tests working in MODE=dbg mode again - The libc/isystem/ headers now have correctly named guards

Get Cosmopolitan into releasable state A new rollup tool now exists for flattening out the headers in a way that works better for our purposes than cpp. A lot of the API clutter has been removed. APIs that aren't a sure thing in terms of general recommendation are now marked internal. There's now a smoke test for the amalgamation archive and gigantic header file. So we can now guarantee you can use this project on the easiest difficulty setting without the gigantic repository. A website is being created, which is currently a work in progress: https://justine.storage.googleapis.com/cosmopolitan/index.html

bool IsElfSymbolContent(const Elf64_Sym *);
Rewrite Cosmopolitan Ar The build/bootstrap/ar.com program is now tinier. This change reduces its size from 140kb to 53kb. Nothing was traded away. Cosmopolitan Ar performance is now 2x better than llvm-ar largely thanks to using the copy_file_range() system call. This change homebrews a new allocation API that addresses the shortcomings of the C standard library design. Using these new balloc() and reballoc() functions I managed to reduce memory consumption so much that Cosmpolitan Ar should now use roughly 100x fewer bytes of peak resident memory compared to llvm-ar. Correct behavior with better compatibility has been assured. Binary output is now pretty much bit-identical to llvm-ar, as of this change. This can and should be the living proof we need to show that a better world is possible for software.
