6d69a29d75 translate-c: Support compound assignment of pointer and signed int 
This handles `ptr += idx` and `ptr -= idx` when `idx` is a

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.

041212a41c zig cc: fix handling of -MM flag 
Clang docs say:
> Like -MMD, but also implies -E and writes to stdout by default.

Previously, Zig handled this option by forwarding it directly to Clang,
and disabling depfiles. However this did not adhere to Clang's documented
behavior of these flags.

Now, in addition to being forwarded directly to Clang, `-MM` also
sets c_out_mode = .preprocessor, just like `-E`.

Another issue I noticed is that Zig did not recognize the aliases for
-MG, -MM, or -MMD. The aliases are now recognized.

98b24aa47f stage2: support environment variables for verbose options 
The presence of ZIG_VERBOSE_LINK now enables --verbose-link.
The presence of ZIG_VERBOSE_CC now enables --verbose-cc.

These are useful when debugging usage of `zig cc` which does not have
CLI flags for these options, since they are not valid C compiler flags.

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.

3ad9cb8b47 zig fmt: allow and trim whitespace around zig fmt: (off|on) 
Currently `//  zig fmt: off` does not work as there are two spaces
after the `//` instead of one. This can cause confusion, so allow
arbitrary whitespace before the `zig fmt: (off|on)` in the comment but
trim this whitespace to the canonical single space in the output.

cd7c870bd8 std: Deprecate 'x'/'X'/'e'/'E' special cases for u8 slices 
Let's follow the road paved by the removal of 'z'/'Z', the Formatter
pattern is nice enough to let us remove the remaining four special cases
and declare u8 slices free from any special casing!
