e280dce30f Translate parameterless C functions (#1978) 
Both FunctionNoProto and FunctionProto are subclasses of FunctionType,
the only difference is that the former is parameterless.

b023db2e82 src/translate_c.cpp: correctly bridge llvm::APSInt with Zig BigInt; 
ACHTUNG: llvm::APSInt stores an int's sign inside of its getRawData; Internally to Zig we store an integer's sign outside of getRawData! (~aps_int) calls .flip() internally on the raw data to match Zig.

test/translate_c.zig: enum: add wider range of values (u64) to try;

dd4b13ac03 Revert "translate-c: Correctly translate enum init values, addressing #1360 (#1377)" 
This reverts commit b8ce8f219c.

Squashing the commits from the pull request resulted in kristopher tate
from being omitted from the authors. A future commit will merge
the code correctly.

breaking syntax change: orelse keyword instead of ?? (#1096) 
use the `zig-fmt-optional-default` branch to have zig fmt
automatically do the changes.

652f4bdf62 disallow unknown-length pointer to opaque 
This also means that translate-c has to detect when a pointer to
opaque is happening, and use `*` instead of `[*]`.

See #1059

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'

2e010c60ae Translate C now correctly converts ints, floats, ptrs and enums to bools 
* Boolean "and" and "or" should also work with these types.
* This new method also simplifies to output code.

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.

8bc523219c add labeled loops, labeled break, labeled continue. remove goto 
closes #346
closes #630

regression: translate-c can no longer translate switch statements.
after #629 we can ressurect and modify the code to utilize arbitrarily
returning from blocks.
