Merge pull request #1175 from bnoordhuis/zig-test-emit-switch 
support --emit in 'test' command

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.

0ebc7b66e6 scope variables in floating point cast tests 
Fixes a bug where the result of a @floatCast wasn't actually checked; it
was checking the result from the previous @floatCast.

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.
