Fangrui Song 141c9d7759 [llvm-dwp] Add SHF_COMPRESSED support and remove .zdebug support 
clang 14 removed -gz=zlib-gnu and ld.lld/llvm-objcopy removed .zdebug support
recently. llvm-dwp currently doesn't support SHF_COMPRESSED. Add support and
remove .zdebug support.

Simplify llvm::object::Decompressor which has no .zdebug user now.

While here, add tests for ELF32LE, ELF32BE, and ELF64BE.

Benjamin Kramer f15014ff54 Revert "Rename llvm::array_lengthof into llvm::size to match std::size from C++17" 
This reverts commit ef82063207.

- It conflicts with the existing llvm::size in STLExtras, which will now
  never be called.
- Calling it without llvm:: breaks C++17 compat

serge-sans-paille ef82063207 Rename llvm::array_lengthof into llvm::size to match std::size from C++17 
As a conquence move llvm::array_lengthof from STLExtras.h to
STLForwardCompat.h (which is included by STLExtras.h so no build
breakage expected).
