f885a1ab61 change async function call syntax
* instead of `async(allocator) call()`, now it is
   `async<allocator> call()`.
 * Fixes syntax ambiguity when leaving off the allocator
 * Fixes parse failure when call is a field access

This sets a precedent for using `<` to pass arguments
to a keyword. This will affect `enum`, `union`, and
`fn` (see #661)

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.

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.
    }

Fixes #731 some more.

0845cbe277 name types inside functions after variable
Before this commit:

    fn f() []const u8 {
        const S = struct {};
        return @typeName(S);  // "f()", unexpected.
    }

And now:

    fn f() []const u8 {
        const S = struct {};
        return @typeName(S);  // "S", expected.
    }

Fixes #675.

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.

 * Enums no longer support field types but they do support
