c5c9d98065 introduce align keyword
* remove `@setGlobalAlign`
 * add align keyword for setting alignment on functions and
   variables.
 * loads and stores use alignment from pointer
 * memcpy, memset use alignment from pointer
 * add syntax for pointer alignment
 * slices can have volatile
 * 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.

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.
