6e2a67724c Revert "another llvm workaround for getelementptr" 
This reverts commit c2f5634fb3df51622cf74f23b4ae0d4a7d2bbbe9.

It doesn't work. With this, LLVM moves the allocate fn call
to after llvm.coro.begin

4ac6c4d6bf workaround llvm coro transformations 
by making alloc and free functions be parameters to async
functions instead of using getelementptr in the DynAlloc block

40dbcd09da fix type_is_codegen_pointer being used incorrectly 
The names of these functions should probably change, but at least
the semantics are correct now:
 * type_is_codegen_pointer - the type is either a fn, ptr, or promise
 * get_codegen_ptr_type -
   - ?&T and &T returns &T
   - ?promise and promise returns promise
   - ?fn()void and fn()void returns fn()void
   - otherwise returns nullptr

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.
