stage2 translate-c: implement functions with no prototype
...
stage1 translate-c actually has this wrong. When exporting a function,
it's ok to use empty parameters. But for prototypes, "no prototype"
means that it has to be emitted as a function that accepts anything,
e.g. extern fn foo(...) void;

translate-c: Emit @ptrCast + @alignPtr sequence
...
Avoid producing Zig code that doesn't compile due to mismatched
alignments between pointers.
Always emit a @alignOf instead of hardcoding the alignment value
returned by LLVM for portability sake of the generated code.

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'

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.
