6edd81109d nullable pointers follow const-casting rules 
any *T -> ?*T cast is allowed implicitly, even
when it occurs deep inside the type, and the cast
is a no-op at runtime.

in order to add this I had to make the comptime value
representation of nullable pointers the same as the
comptime value representation of normal pointers,
so that we don't have to do any recursive transformation
of values when doing this kind of cast.

31aefa6a21 fix structs that contain types which require comptime 
Now, if a struct has any fields which require comptime,
such as `type`, then the struct is marked as requiring
comptime as well. Same goes for unions.

This means that a function will implicitly be called
at comptime if the return type is a struct which contains
a field of type `type`.

fcbb7426fa use * for pointer type instead of & 
See #770

To help automatically translate code, see the
zig-fmt-pointer-reform-2 branch.

This will convert all & into *. Due to the syntax
ambiguity (which is why we are making this change),
even address-of & will turn into *, so you'll have
to manually fix thes instances. You will be guaranteed
to get compile errors for them - expected 'type', found 'foo'

2b3af4ef6b fixed #1009 
ir_make_type_info_defs already calls resolve_top_level_decl on all Tld
when building the def array. This means, that there is no reason that
analyze_fn_body is nessesary, as the fn type should have already been
resolved completly. The only thing analyze_fn_body does here, is cause
problems with generic functions.

36eadb569a run coroutine tests only in Debug mode 
LLVM 5.0.1, 6.0.0, and trunk crash when attempting to optimize coroutine code.
So, Zig does not support ReleaseFast or ReleaseSafe for coroutines yet.
Luckily, Clang users are running into the same crashes, so folks from the LLVM
community are working on fixes. If we're really lucky they'll be fixed in 6.0.1.
Otherwise we can hope for 7.0.0.

90598b4631 fix assert on self-referencing function ptr field 
The construct `struct S { f: fn(S) void }` is not legal because structs
are not copyable but it should not result in an ICE.

9aa65c0e8e allow implicit cast from &const to ?&const &const 
Allow implicit casts from n-th degree const pointers to nullable const
pointers of degree n+1.  That is:

    fn f() void {
        const s = S {};
        const p = &s;
        g(p);   // Works.
        g(&p);  // So does this.
    }

    fn g(_: ?&const &const S) void {  // Nullable 2nd degree const ptr.
    }

And now:

445b03384a introduce std.heap.ArenaAllocator and std.heap.DirectAllocator 
* DirectAllocator does the underlying syscall for every allocation.
 * ArenaAllocator takes another allocator as an argument and
   allocates bytes up front, falling back to DirectAllocator with
   increasingly large allocation sizes, to avoid calling it too often.
   Then the entire arena can be freed at once.

The self hosted parser is updated to take advantage of ArenaAllocator
for the AST that it returns. This significantly reduces the complexity
of cleanup code.

docgen and build runner are updated to use the combination of
ArenaAllocator and DirectAllocator instead of IncrementingAllocator,
which is now deprecated in favor of FixedBufferAllocator combined
with DirectAllocator.

The C allocator calls aligned_alloc instead of malloc, in order to
respect the alignment parameter.

Added asserts in Allocator to ensure that implementors of the
interface return slices of the correct size.

Fixed a bug in Allocator when you call realloc to grow the allocation.

a2bd9f8912 std lib: modify allocator idiom 
Before we accepted a nullable allocator for some stuff like
opening files. Now we require an allocator.

Use the mem.FixedBufferAllocator pattern if a bound on the amount
to allocate is known.

This also establishes the pattern that usually an allocator is the
first argument to a function (possibly after "self").

3671582c15 syntax: functions require return type. remove -> 
The purpose of this is:

 * Only one way to do things
 * Changing a function with void return type to return a possible
   error becomes a 1 character change, subtly encouraging
   people to use errors.

See #632

Here are some imperfect sed commands for performing this update:

remove arrow:

```
sed -i 's/\(\bfn\b.*\)-> /\1/g' $(find . -name "*.zig")
```

add void:

```
sed -i 's/\(\bfn\b.*\))\s*{/\1) void {/g' $(find ../ -name "*.zig")
```

Some cleanup may be necessary, but this should do the bulk of the work.

0ea50b3157 ir: new pass iteration strategy 
Before:
 * IR basic blocks are in arbitrary order
 * when doing an IR pass, when a block is encountered, code
   must look at all the instructions in the old basic block,
   determine what blocks are referenced, and queue up those
   old basic blocks first.
 * This had a bug (See #667)

Now:
 * IR basic blocks are required to be in an order that guarantees
   they will be referenced by a branch, before any instructions
   within are referenced.
   ir pass1 is updated to meet this constraint.
 * When doing an IR pass, we iterate over old basic blocks
   in the order they appear. Blocks which have not been
   referenced are discarded.
 * After the pass is complete, we must iterate again to look
   for old basic blocks which now point to incomplete new
   basic blocks, due to comptime code generation.
 * This last part can probably be optimized - most of the time
   we don't need to iterate over the basic block again.

   clobbers the command line argument data.
   If we were able to verify that the user's code never reads
   command line args, we could leave off this "no inline"
   attribute.
 * add i29 and u29 primitive types. u29 is the type of alignment,
   so it makes sense to be a primitive.
   probably in the future we'll make any `i` or `u` followed by
   digits into a primitive.
 * add `aligned` functions to Allocator interface
 * add `os.argsAlloc` and `os.argsFree` so that you can get
   a `[]const []u8`, do whatever arg parsing you want, and then free
   it. For now this uses the other API under the hood, but it could
   be reimplemented to do a single allocation.
 * add tests to make sure command line argument parsing works.
