translate-c: Use [N:0] arrays when initializer is a string literal (#8264) 
* translate-c: Use [N:0] arrays when initializer is a string literal

Translate incomplete arrays as [N:0] when initialized by a string literal.
This preserves a bit more of the type information from the original C program.

Fixes #8215

a354000090 zig fmt: fix non-UTF-8 encoding #2820 
Fixes #2820

After reading the source code, the first two bytes are inspected, and
if they correspond to a UTF-16 BOM in little-endian order, the source
code is converted to UTF-8.

291edafa1b translate-c: enable pointer arithmetic with signed integer operand 
Given a pointer operand `ptr` and a signed integer operand `idx`

`ptr + idx` and `idx + ptr` -> ptr + @bitCast(usize, @intCast(isize, idx))
`ptr - idx` -> ptr - @bitCast(usize, @intCast(isize, idx))

Thanks @LemonBoy for pointing out that we can take advantage of wraparound
to dramatically simplify the code.

713f113822 stage2: improve orelse implementation 
* Now it supports being an lvalue (see additional lines in the test
   case).
 * Properly handles a pointer result location (see additional lines in
   the test case that assign the result of the orelse to a variable
   rather than a const).
 * Properly sets the result location type when possible, so that type
   inference of an `orelse` operand expression knows its result type.

d4ec0279d3 stage2: add support for optionals in the LLVM backend 
We can now codegen optionals! This includes the following instructions:
- is_null
- is_null_ptr
- is_non_null
- is_non_null_ptr
- optional_payload
- optional_payload_ptr
- br_void

Also includes a test for optionals.

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
```

4f11a88b9f translate-c: Add support for pointer subtraction 
When two pointers are subtracted, both shall point to elements of the
same array object, or one past the last element of the array object;
the result is the difference of the subscripts of the two array elements.

The size of the result is implementation-defined, and its type
(a signed integer type) is ptrdiff_t defined in the <stddef.h> header.
If the result is not representable in an object of that type,
the behavior is undefined.

See C Standard, ยง6.5.6 [ISO/IEC 9899:2011]
