Merge remote-tracking branch 'origin/master' into llvm12

Conflicts:
 * src/clang.zig
 * src/llvm.zig
   - this file got moved to src/llvm/bindings.zig in master branch so I
     had to put the new LLVM arch/os enum tags into it.
 * lib/std/target.zig, src/stage1/target.cpp
   - haiku had an inconsistency with its default target ABI, gnu vs
     eabi. In this commit we make it gnu in both places to match the
     latest changes by @hoanga.
 * src/translate_c.zig
