1a5bd88881 alternate implementation of previous commit 
This strategy adds another field to the SwitchBr instruction,
which is the result of the CheckSwitchProngs instruction. The
type of the result is void, and is unused, except that the SwitchBr
instruction will not perform analysis if the CheckSwitchProngs
instruction did not pass analysis. This allows the CheckSwitchProngs
instruction to do implicit casting for its type checking, while
preventing duplicate compile error messages.

8c39cdc89f fix await on early return when return type is struct 
previously, await on an early return would try to access the
destroyed coroutine frame; now it copies the result into a
temporary variable before destroying the coroutine frame

2759c7951d always link against compiler_rt.o even when linking libc 
sometimes libgcc is missing things we need, so we always link
compiler_rt and rely on weak linkage to allow libgcc to override.

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.
