b988815bf0 parser: fix parsing/rendering of a[b.. :c] slicing 
The modification to the grammar in the comment is in line with the
grammar in the zig-spec repo.

Note: checking if the previous token is a colon is insufficent to tell
if a block has a label, the identifier must be checked for as well. This
can be seen in sentinel terminated slicing: `foo[0..1:{}]`

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.
