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.

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.

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.

2a25398c86 fix segfault when passing union enum with sub byte...
