294ee1bbc9 translate-c: add limited OffsetOfExpr support 
Add support for OffsetOfExpr that contain exactly 1 component, when that component
is a field.

For example, given:

```c
struct S {
  float f;
  double d;
};
struct T {
  long l;
  int i;
  struct S s[10];
};
```

Then:
```c
offsetof(struct T, i)       // supported
offsetof(struct T, s[2].d)  // not supported currently
```

0b58b61799 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

221f1d898c translate-c: Improve function pointer handling 
Omit address-of operator if operand is a function.

57b2176e28 translate-c: Improve array support 
1. For incomplete arrays with initializer list (`int x[] = {1};`) use the
initializer size as the array size.

2. For arrays initialized with a string literal translate it as an array
of character literals instead of `[*c]const u8`

3. Don't crash if an empty initializer is used for an incomplete array.

4. Add a test for multi-character character constants

Additionally lay some groundwork for supporting wide string literals.

800a4a6ceb eliminate dependency of libzigcpp.a on libzigstage1.a

enabled but without the stage1 backend.
