25bbb1a8ff Fix version detection for out-of-source builds 
Git was called in the build directory and not the source directory.
This works fine when the build directory resides within the source
repository, but doesn't work for out-of-source builds. Example:

```
~/zigbuild$ cmake ../zig
fatal: not a git repository (or any of the parent directories): .git
Configuring zig version 0.2.0+
```

Use Git's `-C <path>` flag to always point to the source directory so
that it doesn't matter where the build directory lives.

Merge pull request #1175 from bnoordhuis/zig-test-emit-switch

03f66825d6 support --emit in 'test' command 
Support the `--emit` switch in `zig --emit asm test file.zig`.

The command fails because no tests run (no executable is created) but
it emits the requested file.  That seems like a good tradeoff.

fd75e73ee9 add f16 type 
Add support for half-precision floating point operations.

Introduce `__extendhfsf2` and `__truncsfhf2` in std/special/compiler_rt.

Add `__gnu_h2f_ieee` and `__gnu_f2h_ieee` as aliases that are used in
Windows builds.

The logic in std/special/compiler_rt/extendXfYf2.zig has been reworked
and can now operate on 16 bits floating point types.

`extendXfYf2()` and `truncXfYf2()` are marked `inline` to work around
a not entirely understood stack alignment issue on Windows when calling
the f16 versions of the builtins.

eb6a8e6a3b fix f128 remainder division bug 
The modulo operation computed rem(b+rem(a,b), b) which produces -1
for a=1 and b=2.

Switch to a - b * trunc(a/b) which produces the expected result, 1.
