b8ed0cb374 remove workaround for LLVM not respecting "nobuiltin" 
now that we depend on LLVM 5.0.0 we can remove the
workaround.

closes #393

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.

987768778a bit shifting safety 
* add u3, u4, u5, u6, u7 and i3, i4, i5, i6, i7
 * shift operations shift amount parameter type is
   integer with log2 bit width of other param
   - This enforces not violating undefined behavior on
     shift amount >= bit width with the type system
 * clean up math.log, math.ln, math.log2, math.log10
