   variables.

 * add u2, i2 primitives
 * ignore preferred align and use abi align everywhere
 * back to only having alignOf builtin.
   preferredAlignOf is too tricky to be useful.

d7a539906d Merge branch 'embed-lld' 
Zig now depends on LLVM 5.0.0.

For the latest version that supports LLVM 4.0.1, use
2a49c876be.

Unfortunately we had to embed LLD into Zig due to some
MACH-O related LLD bugs. One of them is already upstream
and another is awaiting feedback on the llvm-dev mailing
list.

You can use cmake option -DZIG_FORCE_EXTERNAL_LLD=ON to
still use external LLD if you want to live with the MACH-O
bugs or if your system LLD is patched.

Closes #273

91536813ec macos updates 
* try some macos travis stuff
 * put c in the link libs for macos since we always link with libSystem
 * for non-native targets on macos, allow runtime symbol resolution
   - it's causing an infinite loop in LLD.
 * for macos, always build compiler_rt and turn on LinkOnce because
   compiler_rt on darwin is missing some stuff.

09bd4a9a86 compile-time f32, f64 operations are now correctly lossy 
previously we used the bigfloat abstraction to do all
compile-time float math. but runtime code and comptime code
are supposed to get the same result. so now if you add a
f32 to a f32 at compile time it does it with f32 math
instead of the bigfloat. float literals still get the
bigfloat math.

2dfb1ebee2 const global values can reference each other 
Before, if you did something like:

```
const hi1 = "hi";
const hi2 = hi1;
```

This would create the "hi" data twice in the built object.
But since the value is const we don't have to duplicate the
data, now we take advantage of this fact.

this reverts 5c04730534.

sadly the quality of the intel dialect in llvm's assembly
parser has many frustrating bugs, and generally has unfortunate

the plan is to use AT&T for now since it at least works,
and eventually zig will have its own assembly parser for
x86 and it will be as close to NASM as possible.

c6605cba83 blocks check that their statements are void 
closes #291

This changes the error message "return value ignored" to "expression value is ignored".
This is because this error also applies to {1;}, which has no function calls.

Also fix ignored expression values in std and test.
This caught a bug in debug.readAllocBytes where an early Eof error would have been missed.

fa7c64ccd5 lazy analysis of top level declarations 
previously, we had lazy analysis of top level declarations,
but if a declaration was referenced within a compile-time

if we analyze the instruction. this takes into account comptime
branching.
